What is Basal Body Temperature (BBT)?. BBT is your lowest body temperature, which occurs before you get out of bed. A woman's temperature fluctuates with the. Basal Body Temperature (BBT) charting may sound like an old-school method of tracking your menstrual cycle, but it's making a comeback. You will need a special “basal body temperature” thermometer, available at drug stores. Some thermometers have a memory feature that records the previous.

What is fertility awareness? How to track fertility using basal body temperature.

What is fertility awareness?

Every month, a woman’s reproductive system undergoes a series of hormone mediated changes, that make it possible for pregnancy to occur. In the first phase of the menstrual cycle (follicular phase), estrogen levels rise gradually, resulting in the thickening of the uterine lining (to prepare for a possible pregnancy) and the growth and development of the oocyte (egg). Around the 14th day,the fully developed egg is released (Ovulatory phase) and is either fertilized by a sperm, resulting in a pregnancy, or is discarded along with the lining of the uterus, resulting in a period (luteal phase).

Usually, the egg is viable for about 24 hours after release. Male sperm cells, however, survive in the female reproductive tract for up to 6 days. So, chances of pregnancy are high, starting from the day before ovulation, lasting up to 6 days after ovulation. 

Fertility awareness methods use physiological indicators to track the time of ovulation and by extension, the 5-7 days of the month when a woman has the highest likelihood of pregnancy.

Women might choose to track their fertility for a number of reasons:

  1. To avoid pregnancy. I.e as a method of contraception
  2. To time intercourse during ovulation, in order to achieve pregnancy
  3. To predict their periods
  4. To establish the presence of an imbalance/ disorder of the reproductive system.

“Basal body temperature (BBT) refers to the lowest temperature of the body, during a state of complete rest (deep sleep). Usually, a temperature reading taken immediately after waking up, even before getting out of bed, is the closest to the basal body temperature”

What are the various forms of fertility awareness?

  • Temperature method
  • Cervical mucus method
  • Calendar method
  • When basal body temperature, cervical mucus and cervical position are monitored together to track fertility, it is known as the “Sympto-Thermal Method” (STM).

What is basal body temperature?

Human body temperature is in a state of constant flux. The body constantly undergoes subtle changes in temperature, reflecting its metabolic patterns. Any number of factors such as exercise, food intake, sleep/wakefulness, stress levels, external temperature and so on, have a measurable impact on body temperature. 

Basal body temperature (BBT) refers to the lowest temperature of the body, during a state of complete rest (deep sleep). Usually, a temperature reading taken immediately after waking up, even before getting out of bed, is the closest to the basal body temperature (although it is still slightly higher than the BBT). 

Because there is so much variability in body temperature, it is vital that the readings used to track your monthly cycles pertain as closely as possible to the BBT and that there is as little variation as possible between them. 

Basal body temperature and fertility

  • During the pre-ovulatory phase of the menstrual cycle, the increased levels of estrogen make for a lower basal body temperature - usually, well below 36.8°C [98.6 °F].
  • Just before the egg is released, the BBT further dips slightly, reflecting the peak concentration of Luteinizing Hormone (LH).
  • And then about 24 hours after ovulation, the higher levels of progesterone released by the corpus luteum raise the BBT by 0.2-0.3°C. This elevation typically lasts until the following menstruation period.
Fertile Days

Most women record temperatures between 36.11-36.38°C [97-97.5°F] before ovulation and 36.44 to 37°C [97.6-98.6°F] right after ovulation, for up to 72 hours, unless pregnancy occurs, in which case, the elevation lasts throughout the first trimester. 

Is It Effective?

Studies show that using BBT charts to track fertility has about a 99% success rate in the first year that most women use it (if done properly). However, following the first year, the success rate drops to about 85%. It is assumed that this is because of reduced assiduousness and care after the initial period. 

BBT charting continues to be a widely used method to track fertility, owing to its affordability, universality and relative simplicity. It is vital to remember however, that there is no such thing as a universally ideal BBT curve. Every woman’s cycle bears its own little idiosyncrasies, which only come to light when the charting is done consistently over a period of time. It is only within the framework of a woman’s unique curves that useful trends are observed. 

How to Chart BBT?

  • You have to measure your temperature every morning, immediately after you wake up, before you move or get up out of bed.
  • The reading has to be taken at about the same time every day; Although some sources say a discrepancy of no more than 30 minutes is probably alright, the accuracy of the method is definitely much more reliable if the time of the readings is kept as constant as possible. Needless to say, the same thermometer needs to be used to obtain the readings.
  • It is essential to get at least 3-4 hours of sleep before you take a reading. If you’ve stayed up all night, the reading taken during the usual time in the morning is to be considered null and void.
  • Note down your readings on an ovulation chart (or on an online or mobile alternative).
  • The longer you track your cycle with meticulous care and regularity, the more accurate it will be with the information it gives you.

Identifying Ovulation

You shouldn’t be surprised to see numerous tiny peaks and troughs in your chart. However do bear in mind that you are looking out for a “curve”. I.e you are looking to find a biphasic pattern that has an ascending and descending trend. This means that after ovulation, the average temperature readings tend to be higher than average readings taken before ovulation.

Three consecutive, above-average readings usually indicate that ovulation probably occurred before the first high reading. 

Abnormal Curves - What Do They Mean?

Generally, as a thumb rule, before you panic about your curve being abnormal, it is advisable to check if your thermometer might be faulty. Additionally, digital thermometers may give slightly-off readings for upto a month before their batteries die. 

  • Monotonous Curve - A curve with no increase or decrease in average BBT, over a month, indicates that ovulation has not taken place.
  • Zig-Zag Curve and Erratic Curve-  These curves indicate a seemingly haphazard rise and fall of BBT over a month. They usually are a sign of estrogen deficiency. If you have notice such curves in your chart, it is advisable to consult your gynaecologist immediately.

Do I Need a Basal Body Thermometer To Chart My Cycles?

No, not necessarily. Although basal body thermometers are especially marketed towards women who are looking to chart their monthly cycles, any thermometer that is accurate and easy to read to within 1/100th of a degree, (if you use celsius - or 1/10th of a degree, for fahrenheit) can be used. 

However, basal body thermometers do come with specialised features that might make them appealing for charting. Nevertheless, you might just find that a few frippery features don’t really justify the prices at which these thermometers are sold.

The Future

The future of healthcare is definitely one that minimises human effort and in turn, error. There is no doubt that medicine is rapidly moving towards a big-data revolution. The consumer of tomorrow will have to do/worry about less and conversely, will have access to more. 

A slice of the future is here - With ONiO, collecting and charting your BBT, readings could not be easier. Readings are collected and tabulated constantly, to reflect trends in your temperature.

Basal body temperature 101 – charting the menstrual cycle 

When we chart the menstrual cycle, one of the most frequently asked questions I receive is: Can I determine ovulation based on the observation of cervical mucus? The answer is no, let’s see why.

Ovulation can only be determined once it has occurred, and the biomarker (read: the physiological signal observable by the naked eye) is the rise in basal body temperature, not the observation of cervical mucus. Before getting into the specifics, let us reiterate a key concept: ovulation can never be predicted, therefore, all methods or apps that predict it are deceiving you (if you are trying to avoid a pregnancy, be warned!). The calendar method, the rhythm method, the basal body temperature-only method, the cervical mucus-only method, and all the apps that predict the day of your next ovulation are unreliable and unfortunately the authoritative fertility awareness methods (FAM in English) based on the symptothermal methodology (i.e. mucus+temperature) are not well known.

Ovulation can only be determined once it has occurred, and the biomarker is the rise in basal temperature, not the observation of cervical fluid. However, if it is a child you are looking for, using only basal body temperature is a serious mistake – you need to use mucus to know when to have penetrative intercourse.

What is basal temperature

Basal body temperature (BBT) is the lowest temperature that your body reaches, normally at night, during sleep.

In the first part of the cycle (menstrual and follicular phase) your BBT will have a rather steady and lower value which we will call X. After ovulation and until the next menstruation, your BBT will rise and have a value that we will call X + 1 degree Celsius.

The rise in BBT is actually  less than 1 degree Celsius, more often it is 0.5-0.8 degrees Celsius, but here we simplify to be clearer.

Why is basal body temperature important?

BBT tells us if we have had anovulatory cycles (which can cause, if sustained over time, a decrease in bone density, and affect heart and breast health, among other things). It tells us how much stress, sleep and food impact on our body; if we have a progesterone deficiency or a shortluteal phase; it will tell you the state of health of our thyroid gland, especially in cases of hypothyroidism. Finally, it reveals the pregnancy about 18 days after fertilization, allowing you and your gynecologist to accurately time your birth date. We will talk about it in detail at the end of the post, stay with us!

Below we see the salient information to start charting it but remember that this information is not for contraceptive purposes. If you want to learn charting as a method of contraception, our founder Anna is a certified teacher of theSensiplan® method, the most reliable method for natural contraception, with a Pearl Index (the efficacy) of 2% (meaning that only 2 people over 100 will get unintentionally pregnant over one year using the method, compared to 9% of the oral pill).

When, what, where to chart basal body temperature?

When: BBT is measured as soon as you wake up, before getting up, talking, drinking or doing anything else (even cuddling your cat, for example).

What: Make sure you have the thermometer handy on your nightstand. The thermometer should preferably be set for basal temperature (average cost, 15 euros). This means that if it is digital, it will have two decimal places and should be accurate to plus/minus 0.1 °C.

If analog, it will have the numbers well-spaced, and will not exceed 38 degrees °C.

How: In one of the following orifices – mouth (under the tongue, between the frenulum and teeth, mouth closed), vagina or rectum. Once you have chosen one, stay with it for the whole cycle. Try to always place the thermometer in the same position. For example, I always put it in the right part of the mouth, under the tongue. If you use the analog thermometer, take it for 3 minutes. The digital thermometer beeps when it is finished but you ignore it and continue for 3 minutes.  BBT should always be taken at the same time to provide a reliable reference. If it is not possible to wake up at the same time (on holiday for example), take note of the different time. If the temperature is higher than your normal fluctuation, put it in brackets and ignore it. Or skip that day and leave the box empty. Box?!? We’ll get to that.

Where: There are several grids to chart the cycle on paper. You can also use an app on the phone if you like (here you can find a table ranking the most reliable apps based on scientific research, but remember to disable the function to predict ovulation). If you want to use pen and paper (the ecological option), you can download and use Medulla’s chart .

Now your expression is more or less like this, isn’t it?

A woman staring in disbelief

It’s actually a lot simpler than it looks! I also looked at it in horror back in 2013. Within three days I had already realized that it was harmless, and within two cycles I was able to fill all the temperature without having nightmares. But I had a teacher by my side, I didn’t do it all by myself. If you need help, you can book a session online or buy our Basal Body Temperature E-Book for €25 by writing to [email protected]

If you want to try it on your own, you are welcome to start by locating the words “Day of the cycle” (the first day of menstrual flow corresponds to day 1) and just below “Date“, where you will put the day of the month (the month and year are at the top). Each day you will mark the corresponding temperature with a dot and then join the dots. Make sure you mark the usual time of your awakening at the top left, and if you wake up at a different time than usual, write it down in the box corresponding to the cycle day/date.

 

Why is the basal temperature rising?

At ovulation, the follicle containing the ovum ready to be fertilized opens, releasing the ovum, which will be taken from the ovary by the uterine tube and begin its crossing to the uterus (which lasts about a week). For a general review there is this short explanatory video which is very nice.

The follicle is dead, kaputt, but… in less than 24 hours it is reassembled and reprogrammed into an endocrine gland (i.e. that produces and secretes hormones) called the corpus luteum. There is nothing in the human body as extraordinary as the corpus luteum follicle, which in such a short time resurrects, changes identity, and becomes operational.  The corpus luteum produces progesterone (the pro-gestation hormone, i.e., necessary to sustain a pregnancy) which speaks to your thyroid gland (another butterfly-shaped gland more or less at neck height) and tells it to raise the temperature of your body.

Soon after ovulation your BBT will gradually increase by about 0.5-0.8 degrees Celsius, although this figure varies from woman to woman. A strong corpus luteum will produce a marked increase. A weaker corpus luteum will produce a smaller rise, but it must be at least 0.2 degrees Celsius. That’s why double decimals, or numerals, are important. We are talking about subtle but perfectly discernible changes with a little practice, a sense of humor, support and patience. Usually it only takes two or three cycles to become a pro, with the support of a certified teacher.

At ovulation, the basal temperature gradually increases by about 0.5-0.8 degrees Celsius, although this figure varies from woman to woman. The minimum increase should be 0.2 degrees Celsius.

The body temperature rises because the corpus luteum builds the nest, in which the fertilized will grow. The nest is naturally our uterus. And it must be warm to be cozy.

This temperature rise must be sustained over time, minimum 10 boxes, maximum 16 boxes. At each cycle, however, the number will always be the same for each of us, for example, for me it is always 13.

BBT can help you identify underlying problems. Let’s see which ones.

The cervical mucus has been super fertile then it disappears, but the temperature is not rising.

If you have observed transparent, elastic mucus and have a wet feeling at your vaginal opening, and after a few days it disappears but the temperature has not increased, you have not ovulated (to better understand what we mean read what your cervical fluid is telling you or watch the videos or write an email to [email protected] to buy our Cervical Mucus E-book for €25).

Ovulation may be delayed or suppressed because the body is under stress. Sources of stress can be industrial food, little movement, illness, travel, intense sports, diets, psychological trauma, severe mental stress such as exams, deadlines, interviews, etc.

However, the body was already preparing for ovulation, which is why the fertile mucus had appeared. If for some reason ovulation does not occur, the mucus will become opaque, creamy and scarcer, and the temperature will not rise.

What to do? Continue to observe mucus and temperature. You’ll probably ovulate after a few days. Fertile mucus will reoccur, and the temperature will rise. If it never rises, and you end up having your period without BBT ever rising up, you can be certain that you have had an anovulatory cycle.

That is to say, ovulation did not take place, the corpus luteum therefore did not form, and the menstruation you see is not really authentic but is the partial result of your partial cycle: you are eliminating the layers of endometrium that had accumulated during the follicular phase of the cycle. In the presence of frequent anovulatory cycles you should consult your doctor to determine the cause. Anovulatory cycles sustained over time can lead to emotional and cognitive decompensation, and loss of bone density or osteoporosis in old age. Of course, if you don’t ovulate you will also have problems getting pregnant.

The temperature rises but is unstable and does not remain high for 10-16 days, returning to the pre-ovulatory phase values.

The problems here might be:

  1. a luteal phase defect (the corpus luteum is weak and dies too soon)
  2. progesterone is weak
  3. there is too much estrogen

The causes for these three problems, which often travel hand-in-hand, can usually be identified and solved within a few cycles by making changes to your diet and routine. To give you an example: if you lead a stressful life, are on a strict or poor diet, do intense sports, little rest, a lot of caffeine, a lot of tablet PC and mobile phone, hostile environments and conflicting relationships, low self-esteem, etc., your body and your mind are constantly washed with abundant cortisol, the stress hormone.

Cortisol takes precedence over everything, and saves us from the dangers of every day, as well as waking up in the morning with a nice peak. Hooray! Too bad that it is built with the same “bricks” of progesterone, and that it jams progesterone receptors on the surface of the cells, so progesterone cannot get in. In short, cortisol blocks or impairs both the production and reception of progesterone. Result: the temperature is unsteady, or it drops and does not return higher.

If you have never charted your menstrual cycle and suffer from this problem, you are likely to be more familiar with the following symptoms:

  • you feel tired but wired
  • difficulty sleeping or staying asleep
  • anxiety, nervousness
  • distraction, poor concentration
  • high blood pressure
  • high blood sugar
  • sugar and carbohydrate cravings
  • migraine and headache
  • breast pain, especially near or at the time of menstruation
  • pain during menstruation
  • abundant and dark-coloured menstrual flow
  • brown spotting before menstruation
  • abdominal swelling
  • premenstrual distress or dis-ease
  • miscarriages or infertility

What to do? Consult a good nutritionist or naturopath to examine your usual diet and routine, and understand how to best nourish body and mind, to restore balance. The results are usually noticeable after a few cycles, and improve your life 360 degrees, as well as rebalancing the menstrual cycle. In doing so, you ensure vitality, calm and clarity.

The temperature in the pre-ovulatory phase (when it is lower) is often below 36.4 degrees Celsius.

Note: in the vagina and rectum the temperature is always higher than in the mouth. Take this into account. Here we refer to a value of 36.4 degrees Celsius in the mouth, under the tongue, around 7am.

In this case our body is telling us that maybe we have a lazy thyroid, or even that we suffer from hypothyroidism. If you have several of the following symptoms, please consult your doctor with your cycle charts and seek advice:

  • dry skin or hair
  • hair loss
  • weak, flaky nails
  • cold hands and feet
  • weight gain and difficulty in losing it
  • tiredness
  • depression, apathy, lack of vitality and interest in the things of life
  • heavy menstrual flow
  • low libido
  • miscarriages or infertility

What to do? You need to get a good endocrinologist to test your thyroid. Ask her what range of values she is referring to (you need a bit of nerve, I know, but with serenity and humility you can ask uncomfortable questions. Remember: this is about your health, not her ego). The range values for the thyroid gland have been updated and often my clients have problems with their doctor, who still refers to the old ones. For example, TSH values were considered acceptable up to 5-6 mIU/L. Now we know that the optimal values are 0.3-2.0 mIU/L (source: Dr Sara Gottfried, The Hormone Cure, Scribner, New York). In addition, you should also test free T3, free T4 and Reverse T3, as some factors can affect TSH, for example, chronic inflammation of the body or intestine.

The basal temperature is an allied sentinel of our equilibrium.

The temperature rises and stays high for more than 16 days.

If the temperature remains high for 16 days or more, congratulations, you are pregnant! Before you sue the Holy Spirit, however, read the following paragraph.

The temperature is unsteady, both before and after ovulation.

Temperature is not always the same, whether in the pre-ovulatory or post-ovulatory phase; this is normal. Provided it varies by a few tenths of a degree. If, on the other hand, yours undergoes great changes, it is possible that the following conditions are occurring:

  1. you’re not taking it correctly
  2. the thermometer is old
  3. you measure it at different times all the time
  4. you’ve had a bad night
  5. you’ve had a late dinner or alcohol
  6. you have an inflammation in progress (sore throat, flu, cold, but also sprained ankle, injury)
  7. You are intolerant or allergic to a food eaten in the last 48 hours.
  8. you’re traveling in a different time zone.
  9. are you under emotional or mental pressure

What to do? If the problem persists once the technical causes (time, position of the thermometer, inflammation and disease) are eliminated, try to keep a diary of everything you do, eat and drink during the day, and try to go three days without eating a given food (the body takes three days to eliminate everything). For example, you have eaten peanuts on Monday, don’t eat them again until Thursday. With a little patience, it will become clear which foods cause inflammation. The most inflammatory foods can be: dairy products made from cow’s milk; sugar, including sugar hidden in packaged foods, as well as fruit juices; gluten; refined vegetable oils; preservatives. The list is incomplete. A good doctor or naturopath can accompany you on this adventure.

Years ago, so did I. I can’t describe to you the feeling I felt once I got rid of food that was harmful to my health. On the contrary, myopic people will understand me: it was like wearing the right glasses after years of obsolete diopters. Good morning world! A new person, bright mental sharpness, new energy and good sleep! Since then, BBT has been helping me to keep the wellbeing of my intestines monitored. If I notice high temperatures, and the only cause can be food, I easily go back to those 3-4 new or unusual foods, and after a couple of weeks of testing, I can generally find the culprit and suspend it for a few months, and then try again and see.

In conclusion

BBT is a real friend, and she’s always happy to tell us what’s going on in our bodies. A sentinel and ally. Charting and interpreting it certainly requires a little patience, humility (because we never stop learning, and because sometimes we need help with interpretation) and a sense of humor (so that it is a source of knowledge and not further stress) but it can largely repay us for the initial effort.

Tracking and interpreting basal body temperature is one of the methods employed by women who want to use natural contraception methods. It is also an indicator of the most fertile period for women who are aiming to conceive. This article helps you understand the ‘why’ and ‘how’ of the process, and guide you in creating a basal body temperature chart for yourself.

What Is Basal Body Temperature (BBT)?

Basal body temperature (BBT) is the lowest body temperature that is attained in a 24-hour period. This would obviously be when you are at rest. A thorough pattern obtained by a few months reading of your BBT will give you a better picture of your ovulation period and timings.

You should measure your BBT before you do any physical activity that might alleviate your body temperature. Ovulation may slightly raise your BBT levels,so noting down your BBT over time may reveal the corresponding variations. That is what makes the BBT a natural method to keep track of your menstrual cycle, especially if you are trying to get pregnant. If you measure your temperature after performing some physical activity, the false and somewhat higher value of BBT can result in wrongly identifying the phase of the menstrual cycle.

BBT levels are known to hike slightly during ovulation. Therefore, recording your temperature over a period of time will show you a pattern and variations whenever they occur. This way, you will be able to keep track of your menstruation cycle which is very helpful if you are trying to get pregnant.

How to Track BBT?

So, how do you measure basal body temperature? Let’s start with the basics first, by learning about the device used to measure it, which is a BBT thermometer.

Basal thermometers or BBT thermometers are recommended over digital thermometers to measure BBT as they are sensitive enough to record the most minute changes that occur in your body as compared to a regular thermometer. Use it to take your temperature the moment you wake up, even before placing your foot on the floor. Since BBT is usually recorded for a 24 hour period, try to wake up at approximately the same time every day for an accurate recording. This could also help regularise your sleep as an added advantage!

The usual value of BBT ranges from 97.2 to 97.7 degrees Fahrenheit,and ovulation could cause an increment in your normal recording by 0.5 to 1 degree. This would last until your period starts and is what will really help you confirm your ovulation. Your BBT could show some spiking on other days apart from your days of ovulation. However, this would only be for a day or two. Once you ovulate, your BBT tends to be at a higher observed value for all readings from that day until you menstruate.

In case you get pregnant after ovulation, BBT would remain high throughout your pregnancy, thus satisfying the condition that it would remain high until your uterus sheds again.

How Does a BBT Chart Help?

Maintaining a chart can make an otherwise seemingly tedious task interesting. It gives you a graph on joining the dots to see the spikes clearly. This kind of a chart can even help your obstetrician diagnose any fertility or other issues related to your menstrual cycle. Moreover, you can boost your chances of conceiving if you keep a track of certain factors related to your cycle on a daily basis.

What Is Cervical Mucus (CM)?

Cervical mucus is the vaginal discharge which is secreted by the cervix and its production is stimulated by the hormone oestrogen. The appearance and quantity of cervical mucus keeps changing depending on your menstrual cycle and on your moods or sexual activity. Most importantly, it protects against infection and irritation.

The consistency, colour and odour of vaginal discharge vary from person to person. However, generally, the colour varies from clear to white to slightly off-white, and the odour from mild to non-existent. There are also patterns observed based on the stage of the menstrual cycle:

  • Soon after your period, there is very little to no vaginal discharge (known as the ‘dry days) because of severely reduced oestrogen activity
  • After this, you may have a thick discharge (also described as cloudy)
  • As you progress towards ovulation, the discharge becomes softer and more liquid in form, allowing for optimum sperm travel (also called the ‘egg white’ stage)
  • After ovulation, the discharge becomes thicker but lesser under the influence of progesterone
  • This will be followed by your period, and the cycle continues

Predicting Ovulation Using BBT and CM

BBT combined with CM can be an effective and natural way for you to track ovulation and plan sexual activity accordingly. It could help know the right time to try insemination or avoid it if you are looking at natural methods to prevent pregnancy.

The signal for knowing when you are at your peak (fertility wise) is a soft, liquid egg-white discharge suggesting optimum conditions for sperm travel right before your ovulation, followed by an increase in your BBT, indicating ovulation.

Noting your CM with your BBT would be a good idea to take charge of things. Note that it will take time for you to develop the habit and notice the patterns.

How to Chart BBT and Cervical Mucus?

If you have a relatively regular cycle, you should be able to plan sexual activity from when you notice the CM becoming egg white and stretchy. You must start trying before the increase in BBT if you want to conceive.

It is better to note the quality of your discharge in the morning. Sometimes you might have to insert a finger up your vagina to clearly examine the nature of your discharge.

Chart your CM and BBT recordings from the first day of your period as soon as you wake up.

Recording Your BBT Chart

There are several templates available on the internet to chart your BBT and CM. We have included a few towards the end of this article. Use the following steps to record your BBT and CM:

  • Begin recording from the first day of your period
  • Plan to wake up at the same time every day
  • As soon as you wake up, even before sitting up, take your BBT reading and mark a point against the day’s temperature reading. (Place your thermometer at an arm’s distance.)
  • Make a note of the date and time
  • Move to the washroom to examine your mucus quality. You could do this before you use the washroom in the morning. If you are checking after, be sure not to wash it all off. You could even observe the CM on the toilet paper after you wipe
  • Make a note of the CM based on the key provided in your chart. For example, the chart from White Lotus Clinic (see below) has CM types as P= period; D= dry; S= sticky rice; E= egg whites
  • As you make recordings, notice that the rise in BBT is usually preceded by the CM turning egg white. The CM turning egg white is when you are most fertile, and a higher BBT will help confirm ovulation.

Phases in BBT Chart

In case you were wondering how to measure basal body temperature, the whole process is explained in a clear manner below. Read through the different phases and know how to mark the chart accordingly.

Women with fairly regular menstrual cycles have two distinct phases in their BBT charts:

  • Follicular Phase – You are in this phase from the first day of your period until ovulation. Higher oestrogen activity leads to low temperatures in the range of 97.2 to 97.7 degrees Fahrenheit. As you approach mid-cycle, there might be a sudden noticeable drop which signifies ovulation.
  • Luteal Phase – After the sudden drop in temperature, BBT shows a sudden spike and remains high for the rest of the cycle due to progesterone activity. This is why the spike in BBT confirms ovulation. BBT ranges from 97.7 to 98.3 degrees Fahrenheit during the luteal phase.

For a lot of women, on impregnation, the graph would show a third phase, a second rise in body temperature of about 0.7 degrees Fahrenheit more than in the luteal phase; 7-10 days after ovulation. Check this completed BBT pregnancy chart to see the third phase.

The answer to the question of how to read a BBT chart is fairly simple and can be explained in a few simple steps. This chart is also called BMT chart (This is for a regular 28 days menstrual cycle).

  • The temperature remains at low values from day 1 to day 13
  • On day 14, when ovulation occurs for most women there is a sudden dip (marking the end of the follicular phase)
  • There is a marked spike on day 15 (beginning of luteal phase)
  • The days from 16 to the next day 1 show fairly higher temperatures than usual. So, you get a BBT graph at the end of each cycle.

You can note the date, day of the week and the time at which you note the BBT. Mark a dot against the temperature observed. Examine CM type according to the key provided and enter the corresponding letter. Tick or cross the days that you had sex on.

Women tend to lose track of their period and often fumble even when asked about the typical lengths of their periods by the gynaecologist.

A lot of symptoms including susceptibility to cold and digestive sensitivities can often be explained based on your menstrual cycle. Also, natural methods are better than any external intervention to plan your pregnancy.

Understanding your BBT chart will help you take things into your own hands and understand the signals your reproductive system gives you. Tracking your BBT and CM helps you plan better at your own end. Whether or not you are planning to start a family, these indicators will surely be of huge importance to make that call.

Why Basal Body Temperature (BBT) for Ovulation Prediction?

Basal body temperature (BBT) is your morning body temperature before getting out of bed and doing any activities. The science behind determining the ovulation using BBT charting is that BBT will rise 0.5 to 1.0 degree Fahrenheit 12 to 24 hours after ovulation, which should last until your next period. So, for many women who have regular BBT chart, you should see biphasic BBT pattern, which shows two levels of temperatures: a pattern of relatively low temps in the preovulatory phase followed by higher temps in the postovulatory phase for about 12 to 16 days. If you can identity when the BBT spike (a.k.a. BBT “thermal” shift) happens, you can assume that the ovulation happened 12 - 24 hours ago with good confidence. Here is a typical BBT chart that shows the biphasic BBT pattern.

Is BBT method effective and useful?

While BBT is a reliable body sign to indicate the ovulation has happened, traditional BBT charting is not the most effective way to determine current fertility windows for conception. Your fertility is highest during the two days before ovulation and the day it occurs, but your BBT spike happens 12 to 24 hours after ovulation. So, by the time you observe the BBT spike, your best fertility time has passed. But, with that being said, BBT spike this cycle can be effective to predict the ovulation days in next cycle if your cycle is regular and you track multiple cycles.

In addition, BBT method requires a lot of effort and commitment to measure and chart BBT manually continuously every morning. Missing a reading or getting an invalid reading may mess up the monitoring for the whole cycle. Besides interpreting BBT chart is also a difficult task for most of TTC women.

Should you still take BBT?

BBT is still an important and reliable body sign to predict the ovulation days if use it properly and consistently. With the bluetooth enabled basal thermometer and smart APP like Premom Ovulation Predictor on your iOS or Android phone, you can take advantage of the benefit of BBT without worry about burden of manual charting and interpretation.

Basal body temperature (BBT) is your morning body temperature before you get out of bed. Charting this temperature over the course of your menstrual cycle is an inexpensive, low-tech way to help determine if you’re ovulating. Because ovulation disorders are one of the major causes of female infertility, many OB/GYNS recommend BBT charting to patients when they first start trying to conceive. This way, doctors can identify and treat any ovulation problems as early as possible.

Contrary to popular belief, BBT charting is not the most effective way to time sexual intercourse for conception. Your fertility is highest during the several days preceding ovulation and the day it occurs, but the change in BBT that indicates ovulation happens 12 to 24 hours afterwards. So BBT doesn’t predict ovulation, but tells you that it happened. If your cycle is regular, tracking your BBT for a couple of months will give you a good idea of when in your cycle you ovulate.

How does measuring BBT help detect ovulation?

A woman’s normal non-ovulating temperature is between 96 and 99 degrees Fahrenheit, depending on the individual. Following the release of the egg, BBT increases by about half a degree in almost all women. The hormone progesterone, secreted by the ovary after ovulation, heats things up; it also prepares the uterine lining for a possible pregnancy. Body temperature will remain roughly half a degree higher until right before menstruation, when it will return to normal. (If you get pregnant, your temperature will stay higher through the first trimester). If your temperature doesn’t follow this pattern, it might indicate an ovulation problem.

Because the spike in body temperature at ovulation is so small, you need a special basal thermometer (available in drugstores) to measure it. A basal thermometer records temperatures in one-tenth of a degree increments instead of the two-tenth increments on fever thermometers.

Basal thermometers come in mercury and digital versions. The mercury BBT thermometers look like fever thermometers, except the divisions between degrees are large and easy to read. These thermometers can be used orally or rectally. Digital BBT thermometers also look like fever models, except they boast special features like an illuminated display (for easier reading on dark mornings). The digital thermometers are used orally. Most thermometers come with several graphs so you can chart your BBT over two to three cycles.

If you don’t detect an ovulation-indicating temperature rise after several cycles, your doctor will give you a blood test to confirm the findings. BBT thermometers are not 100 percent accurate, and some women ovulate even without an increase in temperature. False readings can be caused by a variety of things, including waking up at different times in the morning. Here’s how to get the most accurate results:

•  Take your temperature when you first wake up and are lying or sitting quietly in bed. You need to do the reading at the same time, give or take 30 minutes, every morning.

•  Leave the thermometer on your night table before you go to bed so there’s no need to get up for it in the morning. Shake mercury thermometers down at night or dip them briefly in cool water. Doing the motions in the morning can cause a rise in temperature.

•  Don’t eat or drink anything, even water, before doing the reading.

•  Be aware of factors other than ovulation that can increase BBT: emotional disturbance, stress, a cold or infection, jet lag, drinking alcohol the night before, using an electric blanket.

•  Don’t pull all-nighters: You need to have at least three hours of uninterrupted sleep to get an accurate reading.

Since BBT is usually recorded for a 24 hour period, try to wake up at approximately the same time every day for an accurate recording. This could also help regularise your sleep as an added advantage!

The usual value of BBT ranges from 97.2 to 97.7 degrees Fahrenheit,and ovulation could cause an increment in your normal recording by 0.5 to 1 degree. This would last until your period starts and is what will really help you confirm your ovulation. Your BBT could show some spiking on other days apart from your days of ovulation. However, this would only be for a day or two. Once you ovulate, your BBT tends to be at a higher observed value for all readings from that day until you menstruate.

In case you get pregnant after ovulation, BBT would remain high throughout your pregnancy, thus satisfying the condition that it would remain high until your uterus sheds again.

How Does a BBT Chart Help?

Maintaining a chart can make an otherwise seemingly tedious task interesting. It gives you a graph on joining the dots to see the spikes clearly. This kind of a chart can even help your obstetrician diagnose any fertility or other issues related to your menstrual cycle. Moreover, you can boost your chances of conceiving if you keep a track of certain factors related to your cycle on a daily basis.

What Is Cervical Mucus (CM)?

Cervical mucus is the vaginal discharge which is secreted by the cervix and its production is stimulated by the hormone oestrogen. The appearance and quantity of cervical mucus keeps changing depending on your menstrual cycle and on your moods or sexual activity. Most importantly, it protects against infection and irritation.

The consistency, colour and odour of vaginal discharge vary from person to person. However, generally, the colour varies from clear to white to slightly off-white, and the odour from mild to non-existent. There are also patterns observed based on the stage of the menstrual cycle:

  • Soon after your period, there is very little to no vaginal discharge (known as the ‘dry days) because of severely reduced oestrogen activity
  • After this, you may have a thick discharge (also described as cloudy)
  • As you progress towards ovulation, the discharge becomes softer and more liquid in form, allowing for optimum sperm travel (also called the ‘egg white’ are mushrooms really good for you ovulation, the discharge becomes thicker but lesser under the influence of progesterone
  • This will be followed by your period, and the cycle continues

Predicting Ovulation Using BBT and CM

BBT combined with CM can be an effective and natural way for you to track ovulation and plan sexual activity accordingly. It could help know the right time to try insemination or avoid it if you are looking at natural methods to prevent pregnancy.

The signal for knowing when you are at your peak (fertility wise) is a soft, liquid egg-white discharge suggesting optimum conditions for sperm travel right before your ovulation, followed by an increase in your BBT, indicating ovulation.

Noting capital city bank login CM with your BBT would be a good idea to take charge of things. Note that it will take time for you to develop the habit and notice the patterns.

How to Chart BBT and Cervical Mucus?

If you have a relatively regular cycle, you should be able to plan sexual activity from when you notice the CM becoming egg white and stretchy. You must start trying before the increase in BBT if you want to conceive.

It is better to note the quality of your discharge in the morning. Sometimes you might have to insert a finger up your vagina to clearly examine the nature of your discharge.

Chart your CM and BBT recordings from the first day of usaa health insurance provider period as soon as you wake up.

Recording Your BBT Chart

There are several templates available on the internet to chart your BBT and CM. We have included a few towards the end of this article. Use the following steps to record your BBT and CM:

  • Begin recording from the first day of your period
  • Plan to wake up at the same time every day
  • As soon as you wake up, even before sitting up, take your BBT reading and mark a point against the day’s temperature reading. (Place your thermometer at an arm’s distance.)
  • Make a note of the date and time
  • Move to the washroom to examine your mucus quality. You could do this before you use the washroom in the morning. If you are checking after, be sure not to wash it all off. You could even observe the CM on the toilet paper after you wipe
  • Make a note of the CM based on the key provided in your chart. For example, the chart from White Lotus Clinic (see below) has CM types as P= period; D= dry; S= sticky rice; E= egg whites
  • As you make recordings, notice that the rise in BBT is usually preceded by the CM turning egg white. The CM turning egg white is when you are most fertile, and a higher BBT will help confirm ovulation.

Phases in BBT Chart

In case you were wondering how to measure basal body temperature, the whole process is explained in a clear manner below. Read through the different phases and know what is bbt to mark the chart accordingly.

Women with fairly regular menstrual cycles have two distinct phases in their BBT charts:

  • Follicular Phase – You are in https www t online de login phase from the first day of your period until ovulation. Higher oestrogen activity leads to low temperatures in the range of 97.2 to 97.7 degrees Fahrenheit. As you approach mid-cycle, there might be a sudden noticeable drop which signifies ovulation.
  • Luteal Phase – After the sudden drop in temperature, BBT shows a sudden spike and remains high for the rest of the cycle due to progesterone activity. This is why the spike in BBT confirms ovulation. BBT ranges from 97.7 to 98.3 degrees Fahrenheit during the luteal phase.

For a lot of women, on impregnation, the graph would show a third phase, a second rise in body temperature of about 0.7 degrees Fahrenheit more than in the luteal phase; 7-10 days after ovulation. Check this completed BBT pregnancy chart to see the third phase.

How to Read a Basal Body Temperature (BBT) Chart

The answer to the question of how to read a BBT chart is fairly simple and can be explained in a few simple steps. This chart is also called BMT chart (This is for a regular 28 days menstrual cycle).

  • The temperature remains at low values from day 1 to day 13
  • On day 14, when ovulation occurs for most women there is a sudden dip (marking the end of trustcase app follicular phase)
  • There is a marked spike on day 15 (beginning of luteal phase)
  • The days from 16 to the next day 1 show fairly higher temperatures than usual. So, you get a BBT graph at the end of each cycle.

There are fixed spaces to note every little detail, from the dates covered to the cycle number and specifics for each day of the period. You can note the date, day of the week and the time at which you note the BBT. Mark a dot against the temperature observed. Examine CM type according to the key provided and enter the corresponding letter. Tick or cross the days that you had sex on.

Women tend to lose track of their period and often fumble even when asked about the typical lengths of their periods by the gynaecologist.

A lot of symptoms including susceptibility to cold and digestive sensitivities can often be explained based on your menstrual cycle. Also, natural methods are better than any external intervention to plan your pregnancy.

Understanding your BBT chart will help you take things into your own hands and understand the signals your reproductive system gives you. Tracking your BBT and CM helps you plan better at your own end. Whether or not you are bank of america credit card phone number hours to start a family, these indicators will surely be of huge importance to make that call.

Detecting Pregnancy or Ovulation in Your Basal Body Temperature Chart

Written by the Tempdrop Team

What is a Basal Body Temperature Chart

Detecting pregnancy or ovulation (to achieve pregnancy) is likely the reason you started tracking your basal body temperature (BBT) in the first place. Am I right?

If you're trying toconceivethen your BBT charts will give you the data you need to detect ovulation and pregnancy. 

How? Before we dive into how we detect ovulation and pregnancy let's start by understanding the basics of how to track your BBT and why it's so important. This will give you the necessary foundation to understand your personal charts.

The Basics of Charting 

Body temperature is influenced by the cyclic ebb and flow of hormones in women. While men have a relatively static BBT, women see a noticeable difference in the pattern of their temps before and after ovulation.

In order to get a clear understanding of when you are ovulating or pregnant, you will need to track your BBT daily. You might also consider charting cervical mucus. 

Tempdrop app on smartphone

You can use a regular BBT thermometer (not to be confused with a fever thermometer) to catch a resting temperature as you wake early each morning. This traditional way of temping means you need to get up at the same time every day (usually between 5 and 7 am), follow strict rules about what you can/can’t do before taking your temperature, and deal with disturbances. Or you could buy a Tempdrop! Using a wearable fertility tracker like Tempdrop will make identifying your most accurate BBT seamless!

You will what is bbt to make a note of your daily temperature on your chart. You can use a printable paper-pencil chart or you can use Tempdrop's integrated charting app (or another charting app of your choice).

Once you have a few months worth of data to review you will begin to notice patterns and trends. This information will ultimately help you understand your ovulation time and help you detect pregnancy.

Why is it important?

In the book, The Fifth Vital Sign, Fertility Awareness Educator Lisa Hendrickson-Jack affirms that "your menstrual cycle is a vital sign, just like your pulse, temperature, respiration rate, and blood pressure." That's because your menstrual cycle can tell you a lot about your overall health.

One of the unbiased fertility signs you can track is your basal body temperature (BBT). By taking note of your BBT and observing trends throughout the menstrual cycle you can:

  • Track ovulation
  • Detect pregnancy
  • Avoid pregnancy
  • Recognize and troubleshoot hormonal and other issues

Now that we understand the basics and why its important we can begin exploring how to detect ovulation when using your BBT chart.

Detecting Ovulation Using Your Basal Body Temperature Chart

Unfortunately, BBT alone doesn't predict ovulation but you can confirm that it has happened! If you decide to also track cervical mucus you can identify when your fertile window opens.  

Once you have 2 or more months of charts to review, predicting ovulation for your next cycle will become easier because you'll begin to notice which day of your cycle is your ovulation day based on your thermal shift. 

Thermal Shift Patterns

When glancing at your BBT chart you will see a spike in temperature 1-2 days after ovulation. This is an indicator of your bodies thermal shift from the time before ovulation happens to the post-ovulation phase. 

The most common pattern is the standard thermal shift. This is the one we will discuss in this article. The standard thermal shift is when you notice a series of low temps and then an obvious "shift" of at least two-tenths of narrative fiction books for 1st grade degree, indicating ovulation has happened. Your temperatures will remain at a higher level until the end of that cycle, when your temperatures will dip again and you will get your period (unless of course you are pregnant which we'll talk more about next).thermal shift and ovulation chart

If you are trying to conceive you'll want to consider having intercourse 2 or 3 days before you ovulate. Once you identify ovulation the two-week wait.

How to Detect Pregnancy Using Your BBT Chart

pregnancy test

Detecting pregnancy is fairly simple when reviewing your basal body temperature chart.

As we previously discussed, your temperatures will rise 1-2 days after ovulation. If you're pregnant, you'll notice that your temps stay elevated and don't drop off with menstruation. In the case of successful pregnancy, temperatures will remain elevated beyond the next expected period. If your temp stays elevated beyond 16-18 days then you're probably pregnant.

If you can't wait for the 18 days of high temps to confirm pregnancy, taking a home pregnancy test may indicate a pregnancy 10+ days post ovulation.

What to Remember

Here's the quick guide to detecting pregnancy or ovulation on your basal body temperature chart:

1. From the time of your period to ovulation your temps will be in a lower range.

2. Mid-cycle (might be later if you have irregular cycles) you’ll notice a rise in your basal body temperature.

3. Your temps will stay high until they drop again. (Once your temps rise up for at least 3 days and stay elevated, you'll know you've ovulated).

4. If your temps stay elevated beyond 18 days after ovulation then it's highly likely you are pregnant.

Basal body temperature (BBT) is your morning body temperature before you get out of bed. Charting this temperature over the course of your menstrual cycle is an inexpensive, low-tech way to help determine if you’re ovulating. Because ovulation disorders are one of the major causes of female infertility, many OB/GYNS recommend BBT charting to patients when they first start trying to conceive. This way, doctors can identify and treat any ovulation problems as early as possible.

Contrary to popular belief, BBT charting is not the most effective way to time sexual intercourse for conception. Your fertility is highest during the several days preceding ovulation and the day it occurs, but the change in BBT that indicates ovulation happens 12 to 24 hours afterwards. So BBT doesn’t predict ovulation, but tells you that it happened. If your cycle is regular, tracking your BBT for a couple of months will give you a good idea of when in your cycle what is bbt ovulate.

How does measuring BBT help detect ovulation?

A woman’s normal non-ovulating temperature is between 96 and 99 degrees Fahrenheit, depending on the individual. Following the release of the egg, BBT increases by about half a degree in almost all women. The hormone progesterone, secreted by the ovary after ovulation, heats things up; it also prepares the uterine lining for a possible pregnancy. Body temperature will remain roughly half a degree higher until right before menstruation, when it will return to normal. (If you get pregnant, your temperature will stay higher through the first trimester). If your temperature doesn’t follow this pattern, it might indicate an ovulation problem.

Because the spike in body temperature at ovulation is so small, you need a special basal thermometer (available in drugstores) to measure it. A basal thermometer records temperatures in one-tenth of a degree increments instead of the two-tenth increments on fever thermometers.

Basal thermometers come in mercury and digital versions. The mercury BBT thermometers look like fever thermometers, except the divisions between degrees are large and easy to read. These thermometers can be used orally or rectally. Digital BBT thermometers also look like fever models, except they boast special features like an illuminated display (for easier reading on dark mornings). The digital thermometers are used orally. Most thermometers come with several graphs so you can chart your BBT over two to three cycles.

If you don’t detect an ovulation-indicating temperature rise after several cycles, your doctor will give you a blood test to confirm the findings. BBT thermometers are not 100 percent accurate, and some women ovulate even without an increase in temperature. False readings can be caused by a variety of things, including waking up at different times in the morning. Here’s how to get the most accurate results:

•  Take your temperature when you first wake up and are lying or sitting quietly in bed. You need to do the reading at the same time, give or take 30 minutes, every morning.

•  Leave the thermometer on your night table before you go to bed so there’s no need to get up for it in the morning. Shake mercury thermometers down at night or dip them briefly in cool water. Doing the motions in the morning can cause a rise in temperature.

•  Don’t eat or drink anything, even water, before doing the reading.

•  Be aware of factors other than ovulation that can increase BBT: emotional disturbance, stress, a cold or infection, jet lag, drinking alcohol the night before, using an electric blanket.

•  Don’t pull all-nighters: You need to have at least three hours of uninterrupted sleep to get an accurate reading.

Basal body temperature 101 – charting the menstrual cycle 

When we chart the menstrual cycle, one of the most frequently asked navy federal no down payment mortgage I receive is: Can I determine ovulation based on the observation of cervical mucus? The answer is no, let’s see why.

Ovulation can only be determined once it has occurred, and the biomarker (read: the physiological signal observable by the naked eye) is the rise in basal body temperature, not what is bbt observation of cervical mucus. Before getting into the specifics, let us reiterate a key concept: ovulation can never be predicted, therefore, all methods or apps that predict it are deceiving you (if you are trying to avoid a pregnancy, be warned!). The calendar method, the rhythm method, the basal body temperature-only method, the cervical mucus-only method, and all the apps that predict the day of your next ovulation are unreliable and unfortunately the authoritative fertility awareness methods (FAM in English) based on the symptothermal methodology (i.e. mucus+temperature) are not well known.

Ovulation can only be determined once it has occurred, and the biomarker is the rise in basal temperature, not the observation of cervical fluid. However, if it is a child you are looking for, using only basal body temperature is a serious mistake – you need to use mucus to know when to have penetrative intercourse.

What is basal temperature

Basal body temperature (BBT) is the lowest temperature that your body reaches, normally at night, during sleep.

In the first part of the cycle (menstrual and follicular phase) your BBT will have a rather steady and lower value which we will call X. After ovulation and until the next menstruation, your BBT will rise and have a value that we will call X + 1 degree Celsius.

The rise in BBT is actually  less than 1 degree Celsius, more often it is 0.5-0.8 degrees Celsius, but here we simplify to be clearer.

Why is basal body temperature important?

BBT tells us if we have had anovulatory cycles (which can cause, if sustained over time, a decrease in bone density, and affect heart and breast health, among other things). It tells us how much stress, sleep and food impact on our body; if we have a progesterone deficiency or a shortluteal phase; it will tell you the state of health of our thyroid gland, especially in cases of hypothyroidism. Finally, it reveals the pregnancy about 18 days after fertilization, allowing you and your gynecologist to accurately time your birth date. We will talk about it in detail at the end of the post, stay with us!

Below we see the salient information to start charting it but remember that this information is not for contraceptive purposes. If you want to learn charting as a method of contraception, our founder Anna is a certified teacher of theSensiplan® method, the most reliable method for natural contraception, with a Pearl Index (the efficacy) of 2% (meaning that only 2 people over 100 coldwell banker bain rentals get unintentionally pregnant over one year using the method, compared to 9% of the oral pill).

When, what, where to chart basal body temperature?

When: BBT is measured as soon as you wake up, before getting up, talking, drinking or doing anything else (even cuddling your cat, for example).

What: Make sure you have the thermometer handy on your nightstand. The thermometer should preferably be set for basal temperature (average cost, 15 euros). This means that if it is digital, it will have two decimal places and should be accurate to plus/minus 0.1 °C.

If analog, it will have the numbers well-spaced, and will not exceed 38 degrees °C.

How: In one of the following orifices – mouth (under the tongue, between the frenulum and teeth, mouth closed), vagina or rectum. Once you have chosen one, stay with it for the whole cycle. Try to always place the thermometer in the same position. For example, I always put it in the right part of the mouth, under the tongue. If you use the analog thermometer, take it for 3 minutes. The digital thermometer beeps when it is finished but you ignore it and continue for 3 minutes.  BBT should always be taken at the same time to provide a reliable reference. If it is not possible to wake up at the same time (on holiday for example), take note of the different time. If the temperature is higher than your normal fluctuation, put it in brackets and ignore it. Or skip that day and leave the box empty. Box?!? We’ll get to that.

Where: There are several grids to chart the cycle on paper. You can also use an app on the phone if you like (here you can find a table ranking the most reliable apps based on scientific research, but remember to disable the function to predict ovulation). If you want to use pen and paper (the ecological option), you can download and use Medulla’s chart .

Now your expression is more or less like this, isn’t it?

A woman staring in disbelief

It’s actually a lot simpler than it looks! I also looked at it in horror back in 2013. Within three days I had already realized that it aetna bank of america contact number harmless, and within two cycles I was able to fill all the temperature without having nightmares. But I had a teacher by my side, I didn’t do it all by myself. If you need help, you can book a session online or buy our Basal Body Temperature E-Book for €25 by writing to [email protected]

If you want to try it on your own, you are welcome to start by locating the words “Day of the cycle” (the first day of menstrual flow corresponds to day 1) and just below “Date“, where you will put the day of the month (the month and year are at the top). Each day you will mark the corresponding temperature with a dot and then join the dots. Make sure you mark the usual time of your awakening at the top left, and if you wake up at a different time than usual, write it down in the box corresponding to the cycle day/date.

 

Why is the basal temperature rising?

At ovulation, the follicle containing the ovum ready to be fertilized opens, releasing the ovum, which will be taken from the ovary by the uterine tube and begin its crossing to the uterus (which lasts about a week). For a general review there is this short explanatory video which is very nice.

The follicle is dead, kaputt, but… in less than 24 hours it is reassembled and reprogrammed into an endocrine gland (i.e. that produces and secretes hormones) called the corpus luteum. There is nothing in the human body as extraordinary as the corpus luteum follicle, which in such a short time resurrects, changes identity, and becomes operational.  The corpus luteum produces progesterone (the pro-gestation hormone, i.e., necessary to sustain a pregnancy) which speaks to your thyroid gland (another butterfly-shaped gland more or less at neck height) and tells it to raise the temperature of your body.

Soon after ovulation your BBT will gradually increase by about 0.5-0.8 degrees Celsius, although this figure varies from woman to woman. A strong corpus luteum will produce a marked increase. A weaker corpus luteum will produce a smaller rise, but it must be at least 0.2 degrees Celsius. That’s why double decimals, or numerals, are important. We are talking about subtle but perfectly discernible changes with a little practice, a sense of humor, support and patience. Usually it only takes two or three cycles to become a pro, with the support of a certified teacher.

At ovulation, the basal temperature gradually increases by about 0.5-0.8 degrees Celsius, although this figure varies from woman to woman. The minimum increase should be 0.2 degrees Celsius.

The body temperature rises because the corpus luteum builds the nest, in which the fertilized will grow. The nest is naturally our uterus. And it must be warm to be cozy.

This temperature rise must be sustained over time, minimum 10 boxes, maximum 16 boxes. At each cycle, however, the number will always be the same for each of us, for example, for me it is always 13.

BBT can help you identify underlying problems. Let’s see which ones.

The cervical mucus has been super fertile then it disappears, but the temperature is not rising.

If you have observed transparent, elastic mucus and have a wet feeling at your vaginal opening, and after a few days it disappears but the temperature has not increased, you have not ovulated (to better understand what we mean read what your cervical fluid is telling you or watch the videos or write an email to [email protected] to buy our Cervical Mucus E-book for €25).

Ovulation may be delayed or suppressed because the body is under stress. Sources of stress can be industrial food, little movement, illness, travel, intense sports, diets, psychological trauma, severe mental stress such as exams, deadlines, interviews, etc.

However, the body was already preparing for ovulation, which is why the fertile mucus had appeared. If for some reason ovulation does not occur, the mucus will become opaque, creamy and scarcer, and the temperature will not rise.

What to do? Continue to observe mucus and temperature. You’ll probably ovulate after a few days. Fertile mucus will reoccur, and the temperature will rise. If it never rises, and you end up having your period without BBT ever rising up, you can be certain that you have had an anovulatory cycle.

That is to say, ovulation did not take place, the corpus luteum therefore did not form, and the menstruation you see is not really authentic but is the partial result of your partial cycle: you are eliminating the layers of endometrium that had accumulated during the follicular phase of the cycle. In the presence of frequent anovulatory cycles you should consult your doctor to determine the cause. Anovulatory cycles sustained over time can lead to emotional and cognitive decompensation, and loss of bone density or osteoporosis in old age. Of course, if you don’t ovulate you will also have problems getting pregnant.

The temperature rises but is unstable and does not remain high for 10-16 days, returning to the pre-ovulatory phase values.

The problems here might be:

  1. a luteal phase defect (the corpus luteum is weak and dies too soon)
  2. progesterone is weak
  3. there is too much estrogen

The causes for these three problems, which often travel hand-in-hand, can usually be identified and solved within a few cycles by making changes to your diet and routine. To give you an example: if you lead a stressful life, are on a strict or poor diet, do intense sports, little rest, a lot of caffeine, a lot of tablet PC and mobile phone, hostile environments and conflicting relationships, low self-esteem, etc., your body and your mind are constantly washed with abundant cortisol, the stress hormone.

Cortisol takes precedence over everything, and saves us from the dangers of every day, as well as waking up in the morning with a nice peak. Hooray! Too bad that it is built with the same “bricks” of progesterone, and that it jams progesterone receptors on the surface of the cells, so progesterone cannot get in. In short, cortisol blocks or impairs both the production and reception of progesterone. Result: the temperature is unsteady, or it drops and does not return higher.

If you have never charted your menstrual cycle and suffer from this problem, you are likely to be more familiar with the following symptoms:

  • you feel tired but wired
  • difficulty sleeping or staying asleep
  • anxiety, nervousness
  • distraction, poor concentration
  • high blood pressure
  • high blood sugar
  • sugar and carbohydrate cravings
  • migraine and headache
  • breast pain, especially near or at the time of menstruation
  • pain during menstruation
  • abundant and dark-coloured menstrual flow
  • brown spotting before menstruation
  • abdominal swelling
  • premenstrual distress or dis-ease
  • miscarriages or infertility

What to do? Consult a good nutritionist or naturopath to examine your usual diet and routine, and understand how to best nourish body and mind, to restore balance. The results are usually noticeable after a few cycles, and improve your life 360 degrees, as well as rebalancing the menstrual cycle. In doing so, you ensure vitality, calm and clarity.

The temperature in the pre-ovulatory phase (when it is lower) is often below 36.4 degrees Celsius.

Note: in the vagina and rectum the temperature is always higher than in the mouth. Take this into account. Here we refer to a value of 36.4 degrees Celsius what is bbt the mouth, under the tongue, around 7am.

In this case our body is telling us that maybe we have a lazy thyroid, or even that we suffer from hypothyroidism. If you have several of the following symptoms, please consult your doctor with your cycle charts and seek advice:

  • dry skin or hair
  • hair loss
  • weak, flaky nails
  • cold hands and feet
  • weight gain and difficulty in losing it
  • tiredness
  • depression, apathy, lack of vitality and interest in the things of life
  • heavy menstrual flow
  • low libido
  • miscarriages or infertility

What to do? You need to get a good endocrinologist to test your thyroid. Ask her what range of values she is referring to (you need a bit of nerve, I know, but with serenity and humility you can ask uncomfortable questions. Remember: this is about your health, not her ego). The range values for the thyroid gland have been updated and often my clients have problems with their doctor, who still refers to the old ones. For example, TSH values were considered acceptable up to 5-6 mIU/L. Now we know that the optimal values are 0.3-2.0 mIU/L (source: Dr Sara Gottfried, The Hormone Cure, Scribner, New York). In addition, you should also test free T3, free T4 and Reverse T3, as some factors can affect TSH, for example, chronic inflammation of the body or intestine.

The basal temperature is an allied sentinel of our equilibrium.

The temperature rises and stays high for more than 16 days.

If the temperature remains high for 16 days or more, congratulations, you are pregnant! Before you sue the Holy Spirit, however, read the following paragraph.

The temperature is unsteady, both before and after ovulation.

Temperature is not always the same, whether in the pre-ovulatory or post-ovulatory phase; this is normal. Provided it varies by a few tenths of a degree. If, on the other hand, yours undergoes great changes, it is possible that the following conditions are occurring:

  1. you’re not taking it correctly
  2. the thermometer is old
  3. you measure it at different times all the time
  4. you’ve had a bad night
  5. you’ve had a late dinner or alcohol
  6. you have an inflammation in progress (sore throat, flu, cold, but also sprained ankle, injury)
  7. You are intolerant or allergic to a food eaten in the last 48 hours.
  8. you’re traveling in a different time zone.
  9. are you under emotional or mental pressure

What to do? If the problem persists once the technical causes (time, position of the thermometer, inflammation and disease) are eliminated, try to keep a diary of everything you do, eat and drink during the day, and try to go three days without eating a given food (the body takes three days to eliminate everything). For example, you have eaten peanuts on Monday, don’t eat them again until Thursday. With a little patience, it will become clear which foods cause inflammation. The most inflammatory foods can be: dairy products made from cow’s milk; sugar, including sugar hidden in packaged foods, as well as fruit juices; gluten; refined vegetable oils; preservatives. The list is incomplete. A good doctor or naturopath can accompany you on this adventure.

Years ago, so did I. I can’t describe to you the feeling I felt once I got rid of food that what is bbt harmful to my health. On the contrary, myopic people will understand me: it was like wearing the right glasses after years of obsolete diopters. Good morning world! A new person, bright mental sharpness, new energy and good sleep! Since then, BBT has been helping me to keep the wellbeing of my intestines monitored. If I notice high temperatures, and the only cause can be food, I easily go back to those 3-4 new or unusual foods, and after a couple of weeks of testing, I can generally find the culprit and suspend it for a few months, and then try again and see.

In conclusion

BBT is a real friend, and she’s always happy to tell us what’s going on in our bodies. A sentinel and ally. Charting and interpreting it certainly requires a little patience, humility (because we never stop learning, and because sometimes we need help with interpretation) and a sense of humor (so that it is a source of knowledge and not further stress) but it can largely repay us for the initial effort. Contact Anna if you need help with charting – she is a certified teacher of the symptothermal method Sensiplan®.
