Mom's experience: no need to measure basal body temperature! . Basal temperature Basal temperature 36

Most women, of course, dream of children. Therefore, pregnancy is long-awaited and desired for them. Many women, just assuming the onset of pregnancy, and not being completely sure of its onset, begin to use all kinds of "indicators" of pregnancy, from home tests to folk ones. Many believe that in order to determine pregnancy and its course, it is necessary to measure basal temperature regularly. And what can a basal temperature of 36.6 mean during pregnancy?

It is absent only during the period of implantation of the fetal egg into the body of the uterus. Then, when the pregnancy develops successfully, the amount of the hormone changes and the temperature drops.

Unfortunately, women obsessed with pregnancy forget that each is individual, and each pregnancy proceeds in its own way. Therefore, the measurement of basal temperature becomes just a mania and any deviation of the thermometer indicator from 37.2 degrees causes panic.

Don't panic when you go down! You just need to contact a competent doctor who will examine the woman, conduct the necessary examination. After all, very often many women do not know about the change in basal temperature at the beginning of pregnancy, do not measure it constantly and do not worry about its decrease. So, most likely, it is worth doing, but at the same time being regularly observed by your gynecologist.

There is nothing more difficult and at the same time easier than psychogenic infertility. Its reason is not at all that a woman cannot become pregnant due to improper functioning of the organs, and that she constantly thinks about a probable pregnancy.

If you think about when pregnancy most often occurs in women, you can observe the following pattern. Sexual intercourse is "productive" when a woman does not think about a potential child at all.

Therefore, in order to become pregnant, you simply need to simply give up thoughts about pregnancy.

As examples, we can consider several cases where women managed to achieve a result:

• Registration for IVF. Waiting artificial takes 6 months, and the woman's thoughts about a likely child are frozen for this period.
• Messages from doctors that pregnancy will never occur. As a result, the woman comes to terms with the thought, and stops thinking about the baby.
• A long but ineffective treatment, during which the doctor suggests taking a short break. He invites the woman to visit some resort and in the process of rest she becomes pregnant.
• child through artificial insemination. After the appearance of the first baby, few women will think about a new pregnancy.
• Adoption of a baby. The reaction is similar to the previous option.

Thus, psychogenic infertility is treated, and you can do it without the help of a specialist, despite the difficulties. Take care of yourself and be healthy!

A low basal temperature is a formidable sign: it can indicate the development of dangerous complications.

What you need to know about BT before and during pregnancy? The desire of the expectant mother to learn about pregnancy is quite natural. Basal temperature is one of the key concepts that determine the state of the body in such a crucial period. At each stage of the monthly cycle, the level of hormones changes, and the internal temperature also changes.

What does basal temperature 36.9 mean? During the first phase of the cycle - this may indicate a variant of the norm. Before ovulation, it decreases. If the basal temperature is 36.2, what does this mean? This suggests that the woman had an over-ovulation drop in temperature and that everything is in order in the body. Many expectant mothers ask their doctors: if the basal temperature is 36.4, what does it mean? If this is before ovulation, then the body is working normally. But if such a state is found in the second phase of the cycle or on early dates carrying an embryo, it is dangerous: the patient may develop a serious hormonal deficiency.

After ovulation, the temperature rises. If ovulation has occurred, the basal temperature is 36.9, this indicates a hormonal imbalance and the need for treatment. Pregnancy may be at risk (exactly the same condition occurs if the temperature is above 37.5).

Especially should be attentive to those women who have already encountered the problem of miscarriage of the embryo. For them, it should be measured constantly throughout the pregnancy, since in its second half there may be situations when fading or miscarriage can occur. By checking the schedule, you can draw certain conclusions and, if necessary, start treatment.

In the second half of the cycle, the basal temperature rises slightly to 37 and two. If there is no basal temperature of 36.5 months, this may indicate a serious hormonal imbalance. Treatment in these cases is extremely necessary: ​​if it is not carried out, then infertility can develop with a high degree of probability. In any case, it should be remembered that hormonal ovarian dysfunction cannot be considered safe and that considerable efforts will have to be made to correct it.

A basal temperature of 36.6 after ovulation may indicate the so-called anovulatory cycle. This means that the egg did not develop and did not come out. The level and type of hormones Then the woman changes, which leads to a violation of the reproductive function.

If BT does not decrease after ovulation and there is no retraction before the proposed new cycle, this most likely indicates that pregnancy has nevertheless occurred. To confirm it, you must undergo additional diagnostics. You can do a simple pregnancy test at home. If he showed its presence, then you need to see a doctor for an additional examination. After ovulation, a basal temperature of 36.7 in the second half of the cycle may indicate progesterone dysfunction.

If in the morning the basal temperature is 36.8, what does it mean? If there is no pregnancy, then this indicator indicates that the body is preparing for the onset of a new monthly cycle. But if such an indicator is available during pregnancy, then an analysis of hormones should be urgently taken. Then the early start of treatment will help get rid of problems with bearing.

If the basal temperature in the early stages is 36.9, this indicates the presence of various pathologies. It should be at the level of 37.1 - 37.2, and sometimes more - depending on the individual characteristics of the female body.

In an ectopic pregnancy, the embryo occupies an abnormal position, but at the same time, progesterone continues to be released into the blood. The growth of BT is still taking place. In no case should a rise in temperature be associated with the development of such an abnormal pregnancy. The patient should undergo a comprehensive examination in the presence of the slightest complaints.

Why is BT going down? Women should remember that during pregnancy, any drop in BBT less than 37 is a sign of pathology. This means that there are separate reasons in the body that complicate its normal course. you should consult a gynecologist and never start self-treatment. You can try to measure the temperature again, maybe some inaccuracies were made in such an important procedure.

Sometimes a doctor can detect a low level of progesterone in the body. Such a patient is subject to hospitalization. If this is done on time, then the pregnancy can be saved. It happens that a reduced BBT indicates a missed pregnancy. The level of progesterone is greatly reduced, which is also displayed on the temperature indicator. If the basal temperature is 36.3, what does this mean? This condition during pregnancy can be very dangerous.

What should women pay attention to when lowering BBT? Here are some simple guidelines.

1. Never need to repeatedly measure BT, it still will not give the desired result.
2. If in the second half of the day this indicator falls, this still does not give cause for concern.
3. The temperature should be measured only in the morning, adhering to all the necessary recommendations.
4. The BT indicator is influenced by such factors as stress, physical activity, overwork, intermittent and short sleep. All this should be taken into account in continuous monitoring.
5. If a pregnant woman is sick, then the correct BBT indicator cannot be achieved. Many drugs can both lower and raise the temperature. Going to the doctor in such conditions will be the only right decision, since individual infectious phenomena can adversely affect the natural course of pregnancy.

If, according to the results of measurements, a decrease in basal temperature is established, this indicates the presence of serious deviations in the course of pregnancy. Early treatment of this condition contributes to the preservation of the fetus and the normalization of the disturbed hormonal background of the patient.

In the future, in more detail, separate articles are planned to consider the following issues:

• what does the basal temperature of 36.6 mean before menstruation, after ovulation;
• what does the basal temperature of 36.7 mean before menstruation and after ovulation;
• why there is a basal temperature of 36.8 during the week, at 6 dpo, on the 28th day of the cycle;
• which means a basal temperature of 36.6 on the 18th, 25th day of the cycle.

The menstrual cycle is divided into phases that successively replace each other. Depending on the phase, the content of hormones in a woman's body can both increase and decrease, along with this, the indicators of basal temperature also change.

The norm of basal temperature values

The body of each person has individual characteristics. Therefore, for each woman, the normal values ​​\u200b\u200bof basal temperature are different. In this case, the main criterion is not an indicator of temperature, but the difference in temperature values ​​between the phases of the cycle.

If the female body functions normally, the minimum difference between the temperatures in the first and second phases is at least 0.4 degrees.

In the normal state, in the follicular phase (immediately after menstruation), the level of estrogen in the blood rises, as a result of which a basal temperature of 36.7 degrees is determined. In some situations, the values ​​\u200b\u200bmay be slightly lower, for example, a basal temperature of 36.4 degrees in the follicular phase is not a violation. However, if during this period the basal temperature is 36.1 degrees, this is already a pathology that requires consultation with a specialist.

Before ovulation, the basal temperature is 36.6 degrees. What does the basal temperature of 36.8 mean during this period? A basal temperature of 36.8 at this stage of the cycle is also a normal indicator. On the day of egg maturation, the temperature values ​​increase, and a basal temperature of 36.9 is determined.

What does it mean? This suggests that the level of hormones has increased, and the body is ready for fertilization and fixing the fetal egg in the wall of the uterus. At the time of ovulation, temperature indicators can reach 37.2 degrees. After ovulation, the basal temperature is 36.9 degrees.

Then there is a decrease in temperature values. But here, too, everything is individual - some women have a basal temperature in the second phase of 36.8 degrees, while others have a basal temperature of 36.9 in the second phase. Sometimes, just before menstruation, the basal temperature is 36.9 degrees - this also does not go beyond the normal range.

However, in some cases, a basal temperature of 36.9 degrees before the onset of menstruation may indicate a pathology, so a consultation with a gynecologist will not be superfluous.

Low basal temperatures

As noted above, the values ​​​​of basal temperature are a purely individual indicator and there is no strictly standard. So, for example, a basal temperature of 36 degrees and a basal temperature of 36.5 degrees is a normal individual phenomenon, provided that the difference between the phases is maintained at least 0.4 degrees.

If the temperature difference is less than 0.4 degrees or the average basal temperature is at a low level, this may indicate a violation.

For example, low temperature indicators are observed in such pathologies:

Basal temperature data during pregnancy

During pregnancy, basal temperature is the most important indicator with which you can identify possible disorders at an early stage, up to the threat of miscarriage. Of particular importance are temperature indicators during a delay in menstruation.

A basal temperature of 36.7 with a delay usually means that conception has not occurred. The reason for the lack of menstruation in this case may be a gynecological disorder. A symptom of a violation may also be a basal temperature of 36.8 with a delay.

However, the cause of the delay is not always pathology. Shift menstrual cycle associated, for example, with climate change. Therefore, when drawing up a graph of temperature values, all factors must be taken into account.

If conception has occurred, the temperature will be 37 degrees or more. In a normal state, a basal temperature of 36.7 cannot be during pregnancy. During the bearing of a child, the content of progesterone is increased, which means that temperature indicators are also increased. However, in certain situations, the temperature may be lowered.

It should be noted that it is precisely the persistent decrease in temperature values ​​that is meant. If a basal temperature of 36.8 during pregnancy was detected once, this is not yet a symptom of a disorder. A similar phenomenon rather speaks of the general condition of the woman's body.

The expectant mother should be alerted by low temperature values, which are determined for some time. The basal temperature of 36.6 during pregnancy, in most cases, indicates a threat of miscarriage.

In such a situation, it is necessary to immediately contact a medical institution, especially if low temperature indicators are accompanied by symptoms such as pain, persistent uterine tone, spotting.

The basal temperature of 36.9 during pregnancy may be associated with a deficiency of sex hormones. A decrease in the production of progesterone in the body of a future mother can lead to a miscarriage.

After all, it is progesterone that prevents uterine contractions and, as a result, detachment of the fetal egg.

To establish an accurate diagnosis, a blood test is mandatory. If the reason for the decrease in temperature is a progesterone deficiency, expectant mother special medications containing progesterone are prescribed.

With timely detection of deviations and appropriate medical manipulations, pregnancy can be saved in most cases.

In order to obtain accurate data, it is necessary to measure the temperature, taking into account the following recommendations:

When should you contact a specialist?

If, subject to correct measurements of temperature indicators, significant deviations from the norm are observed for a long time, you should consult a gynecologist for additional medical examination and making the correct diagnosis.

Consultation with a specialist is necessary in such situations:

Basal body temperature control is an effective diagnostic method for pregnancy planning.

Also, graphs of temperature indicators make it possible to identify hormonal disorders in a woman's body (provided that the temperature is measured correctly). Therefore, many specialists today use this simple, but at the same time reliable method of research.

Women who have been planning a pregnancy for a long time know that the basal temperature before ovulation should be lower than that recorded in the second phase of the monthly cycle. The measurement of this value allows you to control the course of many physiological processes of the reproductive sphere. Temperature fluctuations on the graph and their deviations from the norm indicate problems with the female genital area and even help to suggest the causes of these disorders.

What is this technique

Basal body temperature (BT) is a temperature indicator of a woman's body, which is determined rectally. For diagnosis, it is necessary that the body be in a state of complete inactivity for a long time (at least 3 hours). That is why BT is considered reliable, measured in the morning immediately after sleep, when the woman has not yet had time to get up.

Measurement of basal temperature is carried out by inserting a thermometer into the rectum. Most often, women practice a similar technique during pregnancy planning to determine ovulation (an important process when an egg leaves a burst follicle). If you conduct a study regularly and display the results on a graph, you can keep reproductive processes under control, thereby increasing the chances of a productive conception. Such records should be kept from the first day of the cycle (the first day of menstruation) until the beginning of the next menstruation.

There are many subtleties and rules for maintaining and compiling a temperature curve (read the detailed article on how to lead).

What will BT tell in the follicular phase

As you know, the monthly cycle of every woman consists of two phases, separated by ovulation, that is, the moment of rupture of the follicle, from which the egg is ready for fertilization.

The first (or follicular) phase is characterized by a period of maturation in one of the ovaries of the sex gamete. This process does not need high temperature indicators, therefore it proceeds against the background of a lower basal temperature. Its optimal values ​​​​in the first phase are considered to be marks on the thermometer at 36.3 - 36.7 degrees Celsius.

Measurement of basal temperature in the first phase of the cycle allows you to:

• to control reproductive function;
• determine the approach of probable ovulation;
• to diagnose the duration of the follicular phase;
• detect hormonal fluctuations.

BBT before ovulation indicates the level of hormonal activity in the first phase of the menstrual cycle. Normal indicators of basal temperature in the follicular period indicate fairly high titers of estrogen and low levels of progesterone in a woman's body.

It is estrogens that affect the maturation of a normal egg and the adequacy of the preparation of the endometrium of the uterus for the probable implantation (implementation) of the fetal egg. Decreased levels of these hormones are a sign of serious violations of neurohumoral regulation and require careful examination.

ovulation retraction

Approximately 2-3 days before the release of a mature gamete from the ovary, the so-called ovulation retraction is recorded on the graph - a decrease in basal temperature by 0.1 - 0.3 degrees. This is approximately day 11-13 of the cycle, when the follicle reaches its maximum dimensions and getting ready to burst. The fall lasts only a day (sometimes several hours), after which the indicators return to the previous level.

Women are not always able to fix the fall on the chart. It happens that it is too short in time, and does not coincide with the moment of temperature measurement. It happens that it is not due to individual characteristics. So the schedule without ovulation retraction can also be considered normal, unless, of course, the other parameters do not go beyond the normal range.

Ovulation itself is characterized by a sharp increase in temperature in the rectum by 0.4-0.6 degrees, after which it is customary to talk about the onset of the second luteal phase. Throughout its length, BT is kept in the range from 36.8 to 37.3 degrees, which averages 37.0 degrees Celsius.

Only in the case of productive fertilization of the woman's egg by the sperm of her partner on the 7-12th day after conception, there is a decrease in temperature, followed by its rise, which in time corresponds to the attachment of the fetal egg to the endometrium and is called implantation retraction.

Norm and pathology

Changes in the normal schedule of basal temperature indicate the development in the body of a woman of violations of the functioning of her sexual sphere.

Increased BT after menstruation is a sure sign of the development of an inflammatory process in the uterine cavity or on the ovary. Also, a high basal temperature in the first phase may indicate a decrease in estrogen production, which inhibits ovulation and leads to secondary infertility.

According to experts, ideal BT schedules practically do not exist. Normally, every woman encounters anovulatory cycles 1-2 times a year, when a steadily elevated basal temperature is recorded in the first phase without ovulation retraction with a smooth transition to the second period of the monthly cycle.

In this case, there is no cause for concern. You should contact a gynecologist if a high basal temperature after menstruation is diagnosed for 3 or more months in a row and is accompanied by infertility, pain in the pelvic area, menstrual disorders, and the like.

Not always the cause of "bad" schedules are diseases of the genital organs and hormonal dysfunction. Measurement of basal temperature is a process that requires strict adherence to all instructions, and any violation of them leads to a violation of the reliability of the results obtained. The growth of BT indicators is influenced by both external and internal factors, including:

• psycho-emotional upheavals and stress;
• increase in general body temperature;
• taking hormonal drugs;
• drinking on the eve of measuring BBT alcoholic beverages;
• poor sleep and frequent trips to the toilet at night;
• sexual intercourse less than 6 hours before the results were measured.

If the listed reasons for increasing BBT in the first phase of the cycle are absent, the situation is cause for concern. With this scenario, the patient is recommended to seek advice from a specialist and exclude the presence of an inflammatory process in the pelvic cavity using ultrasound diagnostics.

Do you trust this method?

Despite the fact that measurement is one of the most accessible and popular methods, many specialists are not inclined to trust its results. The reliability of such a diagnosis can be influenced by a number of factors that are not related to the state of the patient's reproductive system.

It is important to remember that doctors always make the final diagnosis based on the results of more reliable studies:

• analysis of the level of sex hormones in different phases cycle;
• ultrasound diagnostics of the pelvic organs, in particular folliculometry.

Rectal basal temperature measurement is used by many women to determine their likely ovulation day, allowing them to plan their pregnancy. But you should not trust this technique 100%, since not its results can be negatively affected by a huge number of factors.

Basal body temperature (BT)- the lowest temperature reached after a long rest. This indicator is recommended to be measured by all women planning a pregnancy, since it is a method for calculating favorable days for trying to conceive a baby.

Basal temperature during pregnancy helps to monitor the course of the childbearing period. Its changes can indirectly judge complications - ectopic implantation of an embryo or a miscarriage that has begun. Also, the basal temperature helps to diagnose the onset of pregnancy before the delay.

Basal temperature before pregnancy

The average duration of the menstrual cycle is 28 days. Approximately 12-14 days from the beginning of the last menstruation, ovulation occurs - the release of the female germ cell from the ovary. From this moment, within 3 days, conception becomes possible. With a shorter cycle, it can be observed on days 8-12. With a long cycle, the exit of the germ cell occurs on the 16-18th day, sometimes even later. Some women experience 2 or more ovulations between two periods.

To determine ovulation, you can use or special tests. However, the first method may have low reliability, since in all women the days favorable for fertilization correspond to different days of the cycle. Using an ovulation test is quite accurate, but quite expensive.

BBT measurement - free and effective method ovulation calculation. From the beginning of the cycle, the indicator is 36.5-36.8 degrees. BT depends on the activity of progesterone - the more it is in the blood, the higher the rate. At the beginning of the menstrual cycle, the amount of the hormone is minimal. The low temperature supports the process of maturation of the female germ cell in the ovary.

A day before the release of the female germ cell from the ovary, BT can drop sharply by several tenths of a degree, the next day it rises to 37.1-37.3. With ovulation, a new organ appears - the corpus luteum, which synthesizes progesterone. It is the increase in the amount of the hormone that raises BT to the named values.

By calculating BT, a woman can prevent pregnancy. However, this method of protection is not highly effective, since spermatozoa retain their fertilizing capacity for 7 days after intercourse. For reliable protection against unwanted pregnancy, the calculation of BT should be combined with other methods of protection.

How to measure basal temperature to determine pregnancy?

Basal temperature before delay

Measurement of basal temperature to determine pregnancy is one of the methods for calculating the onset of conception. However, its reliability depends entirely on how correctly the procedure was carried out. If all conditions are met, the measurement of basal temperature will report pregnancy before the delay of menstruation.

In the absence of pregnancy, the corpus luteum synthesizes progesterone for 7-10 days, then it dies off, and the amount of the hormone gradually decreases. Therefore, some time after ovulation, the basal temperature becomes several tenths of a degree lower, amounting to about 36.9-37.0 degrees Celsius. After the onset of menstrual bleeding, these numbers again take values ​​of about 36.7 degrees Celsius.

If pregnancy has occurred, the corpus luteum does not die, but continues to synthesize progesterone, which supports gestation. BT in this case does not fall, and sometimes even becomes higher by one tenth of a degree, amounting to 37.1-37.4.

By measuring BT, one can judge the success of IVF. During in vitro fertilization, a woman is stimulated by progesterone, which increases the values ​​\u200b\u200bof the indicator above 37.1 degrees. With a successful course of the procedure, BT will be in the range characteristic of physiological pregnancy.

The basal temperature in early pregnancy is 37.1-37.4 and can serve as a method for determining the onset of conception and monitoring the process of bearing a child.

Basal body temperature after delay

The onset of the delay corresponds to the 5th week of pregnancy. When the expectant mother does not have an hCG test at hand, she can use the method for determining BT. If its figures are 37.1-37.4 degrees, with a high probability one should judge the onset of conception. When BBT is less than 37.0-36.9, pregnancy is unlikely.

Progesterone, which is responsible for maintaining BT, continues to be actively synthesized by the corpus luteum in the 1st trimester. Therefore, its normal values ​​​​up to 11-12 weeks of gestational age exceed 37.0 degrees.

As the second trimester begins, the corpus luteum begins to gradually decrease in size and produces less progesterone. That is why BT, which is 36.8-36.9 degrees at 16-18 weeks of gestation, is a variant of the norm. From the middle of the 2nd trimester, the corpus luteum does not function, which reduces the amount of the hormone, so the measurement of the indicator has no predictive value from the 20th week.

Rules for measuring basal temperature

Basal temperature in pregnant women can serve as a reliable sign of its normal course only if it is measured correctly. Failure to comply with the rules described below may cause inconsistencies with real numbers and unreasonable worries for the expectant mother. For the correct measurement of basal temperature, you should:

• spend it after waking up, without making movements in bed;
• measurements should be taken at about the same time every day;
• the duration of sleep before measurement should be more than 6 hours;
• the thermometer must be inserted into the anus by 20 millimeters;
• the duration of the measurement must be at least 4 minutes.

The slightest physical activity, sexual intercourse at night before the measurement can cause an increase in blood circulation in the small pelvis, due to which the thermometer will show overestimated values. Also some drugs and infectious diseases provoke an increase in basal temperature. In the evening, there is a physiological rise in the indicator, so even after a long day's sleep, the figures obtained will not correspond to reality.

To track ovulation and monitor the course of pregnancy, a woman can keep a graph of basal temperature. The expectant mother should take a large piece of paper lined in a cage and draw two lines perpendicular to each other.

On the vertical line of the future mother, it is proposed to mark the temperature with an interval of one tenth of a degree, starting from 36.0 and ending with 38.0. Horizontally, a woman needs to arrange the days of the menstrual cycle, starting from the very first.

Next, the woman should note the daily measurements of basal temperature, putting a dot at the intersection of the day of the menstrual cycle and the value obtained. Then the expectant mother needs to connect the dots, thanks to which she will receive line chart. For a more thorough control of the woman it is recommended to sign the symptoms that could provoke an increase in basal temperature- stress, infection, diarrhea, sexual intercourse, etc.

When pregnancy occurs, an implantation drop can be observed on the chart on the 21st day of the cycle (with a menstrual cycle length of 28 days). From 21 to 24 days there will be a slight rise. From the 25th day of the menstrual cycle, the basal temperature will take on a linear form, slight fluctuations of one to two tenths of a degree are possible.

Reasons for a decrease or increase

1. Endometritis.

With this disease, before menstruation, there is a slight drop in basal temperature, as it should be normal. However, on the 3rd-4th day of the cycle, the indicator is more than 37.0 degrees (normally, it should decrease by about 36.5 degrees).

2. Inflammatory process.

Most often, a strong increase in basal temperature above 37.4 degrees indicates an infection. Inflammation can occur in any organ, however greatest influence the indicator is affected by pathologies of the reproductive system (, chlamydia, etc.).

3. Ectopic pregnancy.

Far from always this pathology can be detected by measuring basal temperature. But sometimes, due to the addition of the inflammatory process, there is a rise in the indicator above 37.4 degrees. Up to this point, the basal temperature is normal, since the corpus luteum produces progesterone as in normal pregnancy.

4. The threat of interruption.

Pregnancy with a low basal body temperature of less than 37.0 degrees may indicate progesterone deficiency. With poor functioning of the corpus luteum, there is a constant threat. This condition is often accompanied by pulling or cramping pains in the lower abdomen and lower back, sometimes bleeding is added to them.

5. Frozen pregnancy.

Due to the presence of chromosomal abnormalities or the action of other adverse factors, the embryo may die and not leave the uterine cavity. The basal temperature during a missed pregnancy will be below 37.0-36.9 degrees, since the corpus luteum stops synthesizing progesterone. Usually, intrauterine death is accompanied by other symptoms: a sharp disappearance of toxicosis, a decrease in the mammary glands.

With basal temperature measurement, you can plan auspicious days before conception, find out about pregnancy before the delay and monitor the course of the first trimester. However, this method is not 100% reliable, since there are many factors that affect the correctness of the results.

For the reliability of the results of BT the expectant mother must strictly follow all the rules of measurement. She should remember that even a banal cold or increased physical activity on the eve of calculations can provoke incorrect indicators. Also, the use of low-quality thermometers leads to unreliable results.

The basal temperature in a particular expectant mother may not fit into the above-mentioned norms. In this case, a woman should observe the dynamics of changes in indicators. If during ovulation the basal temperature did not reach 36.5 degrees, it is likely that after conception it will not exceed 37.0. Such results are rare, but they do not indicate complications.

All women are advised to monitor the basal temperature to detect its sharp jump in one direction or another. Any violations in the basal temperature chart do not always indicate the development of pathology. But with a sharp drop or increase in the indicators of the expectant mother, it is recommended to consult a doctor for additional research. Sometimes regular measurements of basal temperature help to diagnose complications such as an ectopic or miscarriage in time.
