Basal body temperature chart 28 days. Low basal temperature during pregnancy: is it worth worrying. Hormonal deficiency: progesterone estrogen

A healthy woman resorts to measurements most often because of the desire to conceive a child. BT during pregnancy is significantly different from the indications that are observed in other periods of life. If there are corresponding indications of BT, which are inherent in pregnancy, then we can talk about a successful conception. BBT also becomes interesting in each period of gestation - from 1 to 40 weeks.

Basal temperature data is taken from three places:

In the mouth.
In the rectum (rectal).
Into the vagina.

The most accurate readings are the temperatures measured in the rectum. They are lowered in the first phase, that is, up to 37°C. They fluctuate from 36.2 to 36.9 degrees, which is individual. The most important thing is that the readings of BT in the second phase (the release of the egg in the fallopian tubes, i.e. after ovulation) were at least 0.4°C higher than the previous ones. This "morning" temperature persists until the onset of menstruation:

For 1-2 days before menstruation, BT falls.
On the day of menstruation increases.

Basal temperature is strictly controlled by the level of hormones produced by the body. During pregnancy in the second phase, the temperature gradually rises or is already high up to a delay in menstruation and even more. This indicates a high level of progesterone and estrogen, which regulate the process of maintaining a pregnancy.

According to the basal temperature, you can calculate the days favorable for conception, as well as periods when you can not worry about the safety of sex. It is also regulated by hormone levels. Basal temperature also helps to identify various deviations in reproductive function. For example, at 3 and 4 weeks of pregnancy (according to obstetric indications), the temperature should be more than 37 ° C.

If there is a delay, however basal rate falls, this indicates a negative process of conception (pregnancy is not observed).

How to measure?

Basal temperature is an easily changing thing. A woman must follow the rules of her measurement in order to get the correct data. These rules are the same for all women: both pregnant and non-pregnant..

One thermometer should be used, which can be mercury (preferably) or digital. It is inserted into the rectum by 2-3 cm and held for 5-7 minutes. Measurements are taken strictly at the same time (the run-up can be up to 30-60 minutes maximum). Everything happens in morning time when the woman had just woken up and had not yet gotten out of bed.

Other rules for scheduling BT are:

Measurements are taken for 4 menstrual cycles in a row for a more reliable picture.
Measurements are taken after waking up from sleep, which should last at least 5 hours. In the morning, a woman should, without getting out of bed and without stretching, take a thermometer and measure the temperature.
While the temperature is being measured, you should lie still.
All data is recorded in a notebook, where the date and exact data on BT are indicated. At the same time, notes are recorded regarding what distorted the BT readings, for example, drinking alcohol or medicines the day before.

Basal body temperature is not taken in daytime. Only in the morning is it reliable. With activity and movement, body temperature rises, which distorts the readings.

BT distortion can be affected by:

Alcohol consumption.
Sexual contact the day before.
Diseases in which the general body temperature rises.

During pregnancy, it should be borne in mind that BBT is within the normal range for 2 weeks after conception. Then there are hormonal changes that distort the data. At week 9, BT will not be of much interest than at week 1 or 2. However, if the doctor has prescribed it to be measured, then his recommendations should be followed.

Diagnosis at an early stage

During pregnancy, BBT remains high until the delay and longer. Diagnostics on early stages produced after conception in the first weeks. The temperature rises to 37 and above (by 0.4-0.5 degrees) and on the day of the delay it will rise by another 0.2-0.3. However, everything is individual: in some women, the temperature may not rise more than 37 ° C.

The BT schedule during the first week will sometimes behave strangely. For example, on the 6th day it may fall basal body temperature, which does not indicate pathologies. Sometimes this happens after ovulation on the 7-10th day, which indicates implantation retraction, which may be accompanied by bleeding.

The next or 2 days after the fall, the temperature rises again to a high level. Such fluctuations in the second phase may indicate fertilization.

Other signs of pregnancy may be following cases(if there was no short-term temperature jump in the second phase):

Increased BBT is observed for 3 days and longer than in previous cycles.
High BBT lasts at least 18 days - a sure indicator of pregnancy.
A third upward temperature jump is observed, dividing the graph into 3 phases.

Low BBT during gestation

You should pay attention to what is the basal temperature when pregnancy occurs. Her normal is 37.1-37.4°C. However, sometimes lower temperatures can be observed. Low BBT is not an alarming sign during the gestation period, but attention should be paid to it.

Often, gynecologists advise measuring BBT during the entire first trimester. This occurs in cases where a woman has previously had miscarriages, the threat of termination or fading of pregnancy. A low temperature in the first trimester may indicate:

Lack of progesterone, which regulates normal gestation.
The threat of spontaneous abortion.
Freezing fetus.

A sharp drop in the basal mark below 37 degrees may indicate insufficient production of progesterone. In this case, a visit to the doctor should be mandatory, especially if other warning signs occur:

Pain in the lower abdomen.
Increased uterine tone.
Bleeding.

You should not panic that BBT has dropped to 36.9 ° C, if there are no discomfort, abdominal pain, bleeding. This is not considered normal, but it may play a role individual characteristics female body. You should be examined by a doctor so as not to worry about low BBT.

If BBT drops to 36°C, this is an abnormal sign. Fetal fading or spontaneous abortion may be noted here. In any case, it is necessary to consult a doctor urgently.

It is also necessary to make a visit to the gynecologist if BT drops to 36.8 degrees and below and keeps long time. Here you may need to get tests for hormone levels. However, if low BBT manifested itself only once, then you should not worry. It could be an error in measurements or a temporary change in the state of the female body.

What does elevated BBT mean?

High BT should also draw attention. What does she say increased performance? If a long time 38 ° C is noted, then you should use medical assistance, since we can talk about inflammatory processes in the body or ectopic pregnancy(BT may be normal in this case).

Slightly elevated BBT (37.7-38°C) is normal, which may indicate the individual characteristics of the organism.

We should not forget about the various factors that affect BBT measurements. If a woman takes medication, leads sexual life, moves after waking up, then the indicators will be different, which is natural.

A slightly increased BBT is quite normal, if at the same time the woman feels good and nothing bothers her, and the level of hormones remains normal.

Internal BT at various stages of pregnancy

Changes in internal BBT at various stages of pregnancy should be considered:

The 3rd week corresponds to the 1st embryonic week. On the this stage BT shows 37-37.5-37.7 degrees and a little higher. A mark below 37 ° C indicates deviations and the threat of termination of pregnancy.
The 4th week is marked by BT indicators in the range of 37.1-37.3 ° C, the maximum limit is 38 ° C. Higher values indicate infectious or inflammatory processes.
The 5th week should be stable within 37.1-37.7 degrees. If it repeatedly rises or falls, then you should pay attention to other signs: drawing pains, hardening of the abdomen, softening of the mammary glands, etc.
The 6th week retains the same indicators: 37.1-37.7°C. If the temperature rises or falls significantly, then we can talk about the death of the fetus.
Weeks 7-8 are marked by BBT values within the range not lower than 37.1-37.3 and not higher than 38 degrees. In case of abnormal indicators, additional health diagnostics (ultrasound) should be performed. By the end of this period, the fetus becomes less susceptible to various factors, however, it is better to continue to maintain a BT schedule.
9-10 weeks should keep the previous indicators in the range of more than 37 and below 38 degrees. AT otherwise medical advice is recommended.
The 11th week is marked by a slight decrease in BBT to 37-37.2°C. If the temperature remains high, then you should consult a gynecologist.
The 12th week is determined by BT marks of 37-37.8, with a maximum of 38 degrees. Ideal indicators are 37.6-37.7 ° C.

In the following weeks, the level of BT remains within the normal range - in the region of 36.6-36.8 degrees. Too high or too low BT indicate hormonal disorders, the threat of miscarriage and other pathologies. At the 40th week, BBT rises to 37.4 degrees or more (by 0.5-0.8 ° C). Before giving birth, some women also have a high fever.

Forecast

Basal temperature helps in solving many problems, including during the entire pregnancy. It’s not enough just to conceive, you still need to endure, which is 40 long weeks. A lot can happen during this period. In order for the prognosis to be favorable, it is necessary to measure BBT throughout the pregnancy in order to note deviations from the norm and seek help in time.

Even 15 years ago, the measurement of BBT was considered one of the main diagnostic methods women's reproductive health. After all, the basal temperature of a non-pregnant woman is fundamentally different from the BT of a girl "in position". A "healthy" temperature graph is not at all the same as that of a girl with problems "in the female part."

Now this method has given way to other, more modern and exact ways diagnostics. Gynecologists prefer to prescribe ultrasound and hormone tests to patients. However, the BT method can still tell a lot both to the girl herself and to her doctor.

unsuccessful attempts to conceive a child for long period time;
suspected violation hormonal balance and change in the menstrual cycle;
probable infertility of one of the partners;
calculation using the schedule of the most favorable days for conception, when ovulation occurs (the release of an egg ready for fertilization from a mature follicle);
control over the processes occurring in the body of a woman;
diagnostics anovulatory cycles.

BT is measured in morning hours after a good night's rest (when healthy sleep lasted at least 6-7 hours), in a state of complete rest and without getting out of bed. As a rule, the most accurate results can be obtained by measuring the basal temperature with a conventional mercury thermometer in the rectal passage, but experts also do not deny the information content of measurements obtained by measuring indicators in oral cavity or vagina.

Based on the results of which a special schedule is drawn up. A competent assessment of the basal temperature chart can only be given by qualified specialist. However, the girl herself can understand a lot.

Cycle phases on the chart

The normal monthly cycle of a woman who is not pregnant consists of two main periods: the follicular and luteal phases. In the first phase of the cycle, which begins with the onset of menstruation, estrogen hormones are actively synthesized in the woman's body, which positively affect the maturation of the egg and the proliferation of the endothelium of the uterus. This period is characterized by consistently low BBT values on the charts, therefore it is called hypothermic.

Approximately in the middle monthly cycle an egg matures in the follicle. Her exit from the ovary or ovulation is accompanied by a change in the hormonal background of the woman, after which progesterone normally begins to be produced - master hormone pregnancy. It's biologically active substance, affecting the centers of thermoregulation in the brain, provokes an increase temperature indicators by about 0.4-0.6 degrees. If fertilization does not occur, progesterone levels begin to decline, menstruation begins, and the body again enters the follicular phase of the cycle.

Temperature norm

Basal temperature in the absence of pregnancy has its own characteristics, which are clearly visible on correctly drawn up charts of the period without conception. The norm is when in the first phase the temperature ranges from 36.3 to 36.6, and in the second it rises by about 0.4-0.6 and is already 36.9-37.1 degrees and above.

So, what should be the basal temperature in non-pregnant women? The non-pregnant basal temperature chart is characterized by the following features:

decrease in BT with the onset of menstruation to the level of 36.3-36.5;
stable level of basal temperature throughout the follicular phase;
rise in BBT indicators about two weeks before the expected menstruation;
the presence of ovulation retraction or a decrease in the level of basal temperature by 0.1 before the release of the sexual gamete from the ovary;
increase in indicators during ovulation to 36.9-37.1;
the temperature difference between the two phases should not exceed 0.4-0.5;
a decrease in the temperature level to 36.7-36.8 one or two days before the onset of menstruation.

Naturally, the graph of basal temperature in the absence of pregnancy differs in many ways from the curves obtained as a result of measuring BBT in women who are already carrying a baby.

The main feature of the graphs without pregnancy is a decrease in the temperature level in the last few days of the cycle, that is, a decrease in progesterone activity. In addition, the basal temperature, if there is no pregnancy (unlike the indicators of women who are expecting a baby), has a two-level view, sinking in the middle of the cycle and a gradual rise in the temperature curve in its second period.

Deviations from the norm

Every woman normally has monthly cycles about twice a year without the release of a mature egg, which are called anovulatory. On such charts, the line is constantly at the same level, without sinking and sharp rises. Anovulatory cycles are characterized by the following features:

the absence of a drop in basal temperature in the middle of the cycle on the charts. The situation when is a confirmation of the absence of ovulation;
in the second phase, no increase in temperature is recorded, since a pregnancy that synthesizes progesterone is not formed.

Graphs of basal temperature will allow you to suspect some diseases of the female genital area. Temperature jumps above 37.0 in the first phase of the cycle indicate the development inflammatory process in the ovaries or uterus. And with a lack of hormones, its relative increase in the first period of the cycle and a decrease in the second will be recorded.

However, it is important to remember that any deviations from the norm on the chart are just an excuse to contact a specialist. By itself temperature measurement- only auxiliary, and not the main method of diagnosis. Perhaps your fears are completely unfounded. Much more reliable laboratory tests, ultrasound and other studies that your doctor will prescribe.

The human body is an amazing and delicate system. On the one hand, in each of us there are typical processes, cycles and situations, on the other hand, in each specific organism they all have their own characteristics. Perhaps the most striking example of this is female body and its reproductive system.

Every woman over the age of 15 is certainly familiar with the menstrual cycle. In any case, with his external resistance - menstruation. However, the essence of the cycle and related processes eludes many. Although knowledge of these processes helps not only to plan your time correctly, taking into account the menstrual cycle, but also to diagnose pregnancy on early dates. But this is the dream of so many women planning a pregnancy.

A schedule for measuring basal temperature during pregnancy before delay can help with this. However, in order for this to become possible, the schedule must be maintained for at least 3-4 months. Only this will allow you to trace the features of changes in basal temperature in a particular woman.

What is basal temperature and how is it measured

We all know from childhood how body temperature is measured - a thermometer under the arm, wait five minutes and see the result. However, few people know that this is how the skin temperature is measured, and no more. Temperature internal organs and cavities will be somewhat different. That is why many doctors now recommend measuring the temperature in the mouth or in the auricle.

And there is also such a thing - basal temperature, or rectal. To find out, the measurement must be carried out in the rectum. Moreover, this must be done strictly certain rules, since a huge number of factors affect basal temperature, starting with physical activity.

How should basal temperature be measured to determine pregnancy in the early stages?

it is important to measure the temperature at the same time, with a difference of no more than 30 minutes;
you need to take measurements in the morning without getting out of bed, you can’t even take a sitting position;
keep the thermometer for at least 5-7 minutes;
it is necessary to take readings immediately after you pull out the thermometer;
the received data are entered into the chart;
must be marked on the chart. possible reasons deviations from the usual schedule, such as a cold, inflammation, and so on.

Why measure basal temperature?

The fact is that the basal temperature changes during the cycle in a certain pattern. At the beginning of the cycle, it decreases, by the time of ovulation, on the contrary, it becomes higher. That is, if you keep a graph of changes in basal temperature, you can calculate the most auspicious days for conception. Usually, it is for this purpose that women take up this occupation. What happens to the basal temperature during pregnancy before the delay? And can BT be considered a sign of pregnancy?

Change in basal temperature during pregnancy

As mentioned above, in the first part of the cycle, approximately starting from 3 or 4 days after the end of menstruation, the basal temperature drops to 36.5-36.8 degrees. This temperature is necessary for the maturation of the egg. The day before ovulation, the temperature drops sharply, and then rises no less sharply to about 37 degrees, sometimes a little higher.

About a week before the onset of menstruation, the basal temperature begins to decrease, unless, of course, pregnancy occurs. What if it comes?

The thing is that the hormone progesterone, which begins to be produced immediately after ovulation, is responsible for the increase in basal temperature during ovulation.

If conception does not occur, then the level of progesterone decreases, therefore, the basal body temperature also decreases. If conception occurs, then the level of progesterone is maintained, and the temperature remains high. Basal temperature during pregnancy before delay is about 37 degrees.

If a woman keeps a chart of basal temperature for several months, then in the event of pregnancy, she will notice that about a week before the onset of menstruation, the basal temperature, instead of the usual decrease, continues to remain at 37 degrees. In this case, you can highly likely assume you are pregnant.

Basal body temperature can be calculated first sign of pregnancy before the delay. However, keep in mind that this is not the most reliable way. The fact is that an increase in basal temperature can be caused by other reasons, including gynecological diseases, infectious processes, physical exercise, taking certain medications, and so on.

Pregnancy is a period when the expectant mother carefully monitors her health. After all, now she worries not only about herself, but also about the life that originated inside her body.

It is very important not to worry for any reason, because unnecessary excitement will not bring any benefits. There are some methods, such as measuring basal body temperature, that will help you constantly monitor your health.

This technique helps to identify some dangerous symptoms. By reacting in time, the expectant mother will be able to protect her unborn baby. If any deviation from the norm is observed, then it is necessary to urgently seek help from a doctor.

What is BT?

Usually it is abbreviated as BT, less often rectal temperature. As the name implies, it is not measured in a standard way- armpits. There are several options for measuring - in the mouth, in the vagina and in the rectum. With its help, ovulation is often tracked when a woman wants to become pregnant.

Normal menstrual cycle more often it shows up to 37 Celsius, but exactly until the moment when ovulation begins - then the temperature rises by 0.4 Celsius. After that, or in 1-2 days, it goes down again. But if this does not happen, then, most likely, pregnancy has occurred.

How much should be during pregnancy? And how long should she stay?

Each organism is individual, but normally - 37.1 - 37.3, exactly the temperature is during ovulation and remains so if pregnancy occurs. It is worth remembering that the borderline norm is 37.0. If there is a deviation of 0.8 degrees in any direction, this is a reason to go to the doctor, or at least you should consult with a physician.

Regarding how long she keeps, the answer is unequivocal - from the beginning of pregnancy and the first few months, while the girl is carrying the fetus.

Why measure BBT?

There are two reasons for this - to monitor the health of the mother and child, as well as to plan pregnancy.

The first reason, as mentioned above, helps to understand whether everything is in order with health. And the second reason helps to calculate ovulation. When a woman wants to have a baby, she needs to determine when ovulation occurs. When there is an increase in BBT, this is a sign that it has come, and now the most Great chance get pregnant.

How to measure it during pregnancy?

Be sure to measure should be carried out in the morning, immediately after sleep, when the body is still at rest. Important point- It is desirable that the sleep is full, at least six hours. You can measure it in any way, but rectal is considered the most reliable. Measurement in this way should be carried out for at least three to four minutes.

oral and vaginal methods measurements will also work, however the time is increased to five minutes. Any thermometer is suitable - both ordinary mercury and electronic. It is advisable to take measurements every day and mark them in a notebook or a special chart - it is easier to track the dynamics. It is necessary to carry out the procedure every time at the same time, the allowable time difference is thirty minutes.

Some factors, such as illness, stress, travel, consumption of alcohol-containing products and even certain medications, can affect the accuracy of the result. Also, do not use contraceptives if you measure rectal temperature.

Norm after conception

Each organism is individual. This can be proved by a simple fact - some people have normal (not rectal) temperature - 36.6, others - 37 and even higher. At the same time, two types of people feel excellent and do not get sick.

So when measuring BT - it all depends on the specific organism. However, you should know the generally accepted and most common norms - from 37 to 37.3. The temperature rises, as a special hormone - progesterone, begins to be produced in large quantities. This happens to protect the fetus.

There were cases when a woman had a rectal temperature - 38, but she was not sick and everything was in order with the fetus. Such cases are very rare, usually, if the temperature is already above 37.3 or below 37, it is wiser to contact the doctors.

Definition of pregnancy by basal temperature

Most likely, a woman is pregnant if the following symptoms are observed:

The temperature is elevated three days after the end of ovulation.
If, with a normal two-phase schedule, a girl observes another jump in temperature (this condition is not considered mandatory).
Phase corpus luteum does not stop for 18 days - that is, the temperature is elevated all this time.

Daily fluctuations in BT

As usual, it is necessary to measure the temperature immediately after sleep, at the same time. The fact is that factors such as light exercise, food, and even clothing can affect the result. Normally, when exactly on the day (not in the morning), it rises above 37.3 - however, the reasons for such an increase are just the factors described earlier.

Therefore, it makes no sense to measure it during the day or even in the evening - you will not understand whether the fluctuations are caused by the usual load on the body or there is reason to worry. Just imagine, in the early stages in the evening, BBT can rise by 1 degree! Morning results are the most reliable, so note them.

Raise

If there is a situation with an increase in body temperature during pregnancy, inflammatory or infectious processes are most likely to occur. But this is only if the increase was fixed correctly, that is, in the morning. Termination of pregnancy in this case is unlikely, but it cannot be discounted.

Regarding an ectopic pregnancy - it may not necessarily cause an increase rectal temperature. Usually it is within the normal range. If this type of pregnancy is disturbed, the woman may feel severe pain in the abdomen, there may even be bleeding. In this case, you can not postpone, you should call an ambulance.

The fall

This also happens. Its fall, especially sharp, should alert. This means that there is insufficient production of hormones. This clearly indicates that the body is not able to support the female body during pregnancy.

If, along with a decrease in rectal temperature, you notice symptoms such as pain in the abdomen, bleeding, prolonged tone of the uterus, then consult a doctor, you should be examined.

A frozen pregnancy usually shows a result below 37, but even in this case, you should not panic, but contact a medical institution.

When and how to measure?

In the morning, without getting out of bed, at rest and with minimal activity. To do this, you need to take a thermometer and place it in the vagina or rectum for two centimeters. Hold the thermometer for three to five minutes.

It is necessary to measure BT every time with the same method, that is, choose one - rectal or place a thermometer in the vagina. The thermometer cannot be changed either, as well as the time of measurement - if you decide to measure at 8.00 in the morning, then continue in the same spirit. Oscillations can be up to thirty minutes in both directions.

In order to carry out the procedure as accurately as possible, here are a few rules that must be followed:

Do the procedure in horizontal position and in no other way, don’t even turn on your side, all the more you can’t squat.
You need a full sleep - from five hours.
It is advisable not to have sex while you are monitoring temperature changes. Or at least maintain a gap of half a day between the measurement and sexual intercourse.
You can not take drugs - they both lower and increase BBT. It is worse when they increase it - you may have it below the norm, and you will think that it is in order.
Eat breakfast only after the procedure.
Try not to get sick - even a sore throat can distort the performance.

Why is a schedule needed?

If the expectant mother wants to seriously monitor this indicator, then you can’t do without a schedule. Different circumstances can affect rectal temperature, especially in the first months of pregnancy.

Usually, the fluctuations on the chart look like this:

On the day of conception - from 36.4 to 36.7.
The next three or four days there is an increase of 0.1, that is, it can reach 37 degrees.
The next two or three days, the value may remain the same.
On the day of implantation gestational sac in the uterine mucosa, it decreases to 36.5-36.6 degrees.
Further three the day is coming a smooth increase and is achieved from 36.7 to 37.
The next fourteen days the value ranges from 36.7 to 31.1. It is important to monitor whether it has fallen below the value that was during ovulation.

It is important to indicate in the schedule not only the numbers, but also the possible circumstances that influenced them - illness, stress, reception medical supplies etc. The attending physician should be aware of them.

How to correctly compose and decipher a graph: a detailed guide

You can draw it yourself, or find it on the Internet and print it. Include the following in your schedule:

"Pregnant" charts

It is impossible to measure everything with one graph alone, discrepancies are acceptable. At different women there are different indicators. Here, for example, some do not observe implantation retraction, or there are several of them at once.

It happens that the temperature rises sharply, or, conversely, smoothly. Sometimes it does not rise above 37. All the options described are defined by physicians as the norm.

Is it possible to determine pregnancy with a thermometer without a chart?

You can, for this you need to follow the rules:

In the evening, shake the thermometer and put it next to, but not under the pillow. The main thing is that it is convenient for you to get it without using sudden movements;
In the morning, without eating, and without even getting up, use a thermometer. Choose either rectal method or place a thermometer in your vagina. It must be placed two centimeters;
Wait three to five minutes;
If the indicator is above 37, you are probably pregnant.

But you can not count on accuracy, an increase can signal an inflammatory process, infection, hormonal failure or normal stress.

Factors affecting performance

To get a reliable result, exclude the following situations:

Taking medication;
Use of contraception (oral or spiral);
Banal lack of sleep;
Consumption of alcoholic beverages;
Sex less than six hours before measurement;
Overwork;
Any illness;
Increased normal temperature.

Is it necessary to control during pregnancy?

It makes sense to do this during the first months. It remains elevated until the twentieth week after conception. Usually, not only gynecologists, but even endocrinologists vote for the control of BT.

With the help of BBT measurement, deviations can be noticed in time and reacted to them. Low performance may signal a threatened miscarriage. Therefore, the answer is unambiguous - it is desirable to control it. However, this is not the only way state diagnostics future mother and her child.

At different stages of pregnancy

Consider the basal temperature at various stages of pregnancy:

Week 3 corresponds to the 1st embryonic week. BT shows from 37 to 37.7 and slightly higher. The mark below indicates deviations and the danger of miscarriage.
N. 4 in the range from 37.1 to 37.3 °, maximum - 38. If higher, then it is possible that this is an infection.
H. 5 is stable from 37.1 to 37.7. If it “jumps”, then pay attention to other signs: drawing pains, hardening of the abdomen, softening of the mammary glands, etc.
N. 6 retains the previous results: from 37.1 to 37.7. If it rises or falls significantly, fetal death is possible.
N. 7-8 from 37.1-37.3 (not lower) and not higher than 38. In case of non-standard indicators, undergo additional health diagnostics (ultrasound).
N. 9-10 - as during weeks 7-8, but more than 37 and below 38. If this is not the case, consult a doctor.
N. 11 decrease from 37 to 37.2. If it is still high, then consult a gynecologist.
N. 12 from 37 to 37.8, but not higher than 38. Ideal are from 37.6-37.7 °.

The last weeks show from 36.6 to 36.8. At the fortieth week, it rises to 37.4 and can rise immediately before childbirth.

Deviation from the norm

If it deviates from the norm, then it is either ovulation or pregnancy. During pregnancy, the doctor often recommends that you measure it to eliminate the risk. Especially often this method is recommended for those who have previously experienced a miscarriage or problems during gestation.

Why is she too tall?

This may be due to an infection, due to an inflammatory process, or even an ectopic pregnancy. In this case, you need to monitor some other signs: does the stomach hurt, what color is the discharge (normally transparent). If you see them, you need to do an ultrasound.

Possible threat of interruption

This is signaled by a decrease in BT. The decrease is due to a lack of progesterone production. If the result falls below 37, in addition, abdominal pain and discharge are felt. Brown need to seek help urgently.

Frozen pregnancy

Unfortunately, in this case, you will have to extract the fetus, it threatens the woman's life. It does not always come out on its own, because of this you will have to seek medical help.

Other signs that signal the fading of the fetus are the absence of toxicosis, the mammary glands no longer increase.

Is there a low BBT during normal pregnancy?

It is difficult to talk about norms - they are always conditional. Not always low temperature interferes with bearing a fetus, women give birth to healthy babies and nothing threatens their lives. In addition, there may be such an option - during ovulation, just before conception, the temperature was 36.4, so it is unlikely that it will reach 37 during the next two weeks.

However, if there are such signs - pain or opaque discharge - you should go to the doctor.

Basal temperature of a healthy woman

The norm is not lower than 36.2, but not higher than 37.2. Before ovulation, the temperature drops, while it rises - this determines the most probable moment for conception. After conception, it practically does not decrease.

Signs of probable infertility according to the schedule

This is indicated by the following:

The average of the second phase of the cycle (after the temperature rises) exceeds average the first phase by less than 0.4 degrees.
In the second phase of the cycle, the temperature drops change (it is below 37).
The rise in temperature in the middle of the cycle lasts more than three to four days.
The second phase is short (less than eight days).

Schedule for ovulation stimulation

With, especially clomiphene (clostilbegit) and using, in the second phase of the MC, the rectal temperature graph usually becomes “normal”. Two-phase, with a pronounced phase transition, with enough high temperature in the second, with characteristic “stages” (the temperature rises twice) and a slight drop.

If the schedule during stimulation is disturbed and deviates from the norm, this may indicate an incorrect selection of the dose of drugs.

An increase in the first phase during stimulation with clomiphene also occurs with individual sensitivity to the drug.

When to contact a gynecologist?

If you are serious about BBT and see a problem for two cycles in a row, see your doctor. However, he should not prescribe drugs only on the basis of the schedule, you should be referred for other types of examinations. Pay attention to such factors:

Novulatory charts.
Constant cycle delays, while pregnancy does not occur.
