Every woman should take care of her health. For this, it is necessary to visit a gynecologist every six months, if there are no deviations in well-being. Many diseases in initial stage development may be asymptomatic.

To determine possible malfunctions in the systems of the female body, it is recommended to draw a graph of basal temperature. Any physiological and pathological changes be able to identify measurements.

The concept of basal temperature

Basal temperature (BT) is the temperature of the body's blood during sleep. It is measured in the rectum. It is also possible to determine it in the vagina or in the mouth. But cyclic fluctuations can show rectal temperature. This is due to the peculiarities of the blood supply to the ovaries. Other measurement methods are also able to capture cyclic fluctuations, but only when they are pronounced.

Only rectal temperature can determine subtle changes in heat transfer in the ovarian vein. Two things need to be clear:

1. If there is no possibility (or desire) to regularly measure BBT rectally, it is better not to use this method at all.
2. The basal (rectal) temperature graph is not used for diagnosis and treatment.

Any deviations from the standards should be dealt with together with the gynecologist.

Purpose of the method

To correctly understand what basal temperature is, you need to understand how this method is useful. Its main advantage is the ability to clearly define the processes of each phase of the cycle and identify possible deviations in the work of the body.

The norm, which is established by medical specialists, is the ideal. Each organism has its own characteristics. In order to take them into account and be able to draw a correct conclusion, observations are carried out for at least 3 months. The basal temperature chart is recommended for several reasons:

1. The method allows you to determine the moment of ovulation and highlight the days favorable for conception.
2. Rectal temperature during pregnancy changes in a certain way. This suggests that a woman in a position on early dates.
3. Measurement of BBT helps to determine the causes of infertility.
4. It makes it possible to detect the presence of pathologies in the body.
5. With it, you can check the quality of the endocrine system.

However, it is possible to achieve sufficient information content of the method only if the rules for constructing a BT chart are followed. In order to adequately draw it, it is necessary to clearly fulfill a number of requirements.

Data Collection Rules

Rectal temperature is measured by certain rules. The correctness of the result depends on this. The method has a number of requirements:

1. Data collection is carried out at the same time with a maximum deviation of 30 minutes.
2. The thermometer should be prepared in advance so that you do not have to get out of bed. You should move as little as possible, otherwise the temperature will rise by 0.1-0.2 divisions of the thermometer. This will affect the decoding of the result.
3. Measurement is carried out daily, including the phase of menstruation.
4. Continuous sleep before the next measurement of BT should be at least 4 hours.
5. Illness, stress, increased loads affect the result. Therefore, in the presence of such facts, notes should be made in the notes.
6. You must use the same thermometer. A mercury device is preferable, although an electronic version can also be used.

All results are immediately logged. On their basis, a graph is built.

Plotting

To make the results of data collection easier to interpret, they are usually presented in graphical form. Deciphering such information should be done qualified specialist. A woman can independently build such graphs in several cycles.

It is possible to draw a drawing manually or use the program online. This will facilitate the diagnostic process for the gynecologist.

Graphing technology

All measurements recorded in the log must be presented in graphical form. If it is preferable to make a drawing by hand, you should take a sheet in a cage and draw an x-axis (X), on which each cell corresponds to a day menstrual cycle. Accordingly, the ordinate axis (Y) is assigned to degrees. One cell is equal to 0.1 division of the thermometer.

The entire cycle must fit on one sheet. You should not enter readings for several periods on one chart. This leads to errors and difficulties in deciphering.

Basal temperature 37.0 is an important boundary in this study. Therefore, a line parallel to the x-axis is drawn at this level. All measurement results are plotted on a graph in the form of points. Then they are connected in series. The norm is determined only after several months of research.

Exists a large number of programs on the Internet that simplify the process of plotting. The results of the study are entered into the corresponding cells online. The program will build a flat schedule. This approach is as informative as drawing by hand.

Graph notes

Basal temperature in early pregnancy and during the cycle without conception are different. However, to see this difference, it is necessary to perform the study correctly.

Any little thing that used to be a woman could not pay attention, can affect the result. Therefore, it is necessary to record not only the readings of the thermometer, but also a number of additional data. Without them, basal temperature in early pregnancy can easily be perceived as a deviation or go unnoticed at all. Factors that can affect BT include a number of conditions:

• Diseases with an increase general temperature body.
• Intimacy in the evening or at night.
• Alcohol intake.
• Short sleep period.
• Unusual measurement time.
• Sleeping pills.

The basal temperature chart is allowed to be drawn, skipping single unreliable data. This should be noted in the notes. The type of discharge from the genital tract is also indicated here daily.

With the onset of pregnancy, gynecological diseases, hormonal disruptions their character changes.

Normal Graph Type

The individual characteristics of a woman's body affect the type of graph. The norm for each representative of the fair sex is different. However, there are general principles, allowing you to understand what should be the basal temperature.

The following statements are considered examples of normal graphs. They are considered in the context of the cycle with conception and in its absence.

Normal schedule of the period without conception

To answer the question of what basal temperature a non-pregnant girl should have, you need to consider the features of the menstrual cycle. It consists of follicular and luteal phases.

In the process of maturation of the egg, estrogen is produced, and after it is released into fallopian tube the amount of progesterone in the blood serum increases. From the first day of the cycle (the beginning of menstruation), BT drops to the border of 36.3–36.5 degrees. She stays like this follicular phase.

2 weeks before the expected date next menstruation there has been a sharp rise in performance. A basal temperature of 37.0–37.2 indicates that ovulation has occurred.

Moreover, the difference between the second and first phases should be 0.4–0.5 degrees.

This process is influenced by progesterone, which is intensively produced in the luteal phase. It prepares the body for a possible pregnancy. If it has not come, then 24–48 hours before menstruation, measurements will show a gradual decrease to 36.8–37.0 degrees.

Norm during pregnancy

Many couples are interested in what basal temperature during pregnancy is considered normal. This is a really important indicator. When pregnancy occurs, progesterone is actively produced. He is responsible for the processes of the correct flow of this state.

Rectal temperature during pregnancy in the first obstetric weeks is completely identical to the schedule without conception. The norm of BT after ovulation in this case is recognized in the range of 37.0–37.2 degrees.

One of the first signs of a successful conception is the absence of a decrease in this indicator before the day of the expected menstruation.

If there is a fact of delay at a high level of the measured indicator, you should consult a doctor. Having passed the appropriate examination, the gynecologist will be able to accurately diagnose the cause of this condition.

Also, the graph will clearly show the implantation drop in temperature over several days. It has to do with attaching gestational sac in the uterine cavity and occurring hormonal changes. All these factors lead to a temporary drop in the curve on the graph.

The basal temperature during pregnancy remains high, which indicates a sufficient amount of progesterone.

Deviations from the model schedule

The norm of indicators of basal temperature is determined after consultation with a doctor. Only medical specialist based on the examinations carried out, it will help to adequately understand the signals of the female body. Deviations in the course of various processes can be caused by various factors.

Hormonal disbalance

Incorrect production of progesterone and estrogen is displayed on the drawing as the absence of a sharp jump in temperature in the middle of the cycle. If ovulation has not occurred this month, the curve of indicators will not have any sharp rises or falls. Luteal phase deficiency is characterized by a duration of less than 12 days.

A basal temperature during pregnancy of 36.6–36.9 also indicates insufficient production of progesterone. This threatens spontaneous abortion. You need to go to the hospital immediately.

But estrogen deficiency is determined by a high level of temperatures in the follicular phase. If this figure is above 36.7 before the middle of the cycle, you should consult a medical specialist.

Inflammatory processes

In addition to the hormonal disorders listed above, the graph can show the presence of inflammatory processes. This situation is reflected in the form of fluctuations in the curve and an increase in temperature.

With inflammation of the appendages, such a picture will not even allow you to determine the moment of ovulation. Sharp declines and ups indicate deviations of an inflammatory nature.

Raise rectal temperature before the next menstruation allows you to suspect the development of endometritis. The graph will show a slight decrease in the curve in last days cycle, and then its increase to the level of 37.0.

If you haven't started your period, you may be pregnant. But in her absence similar condition indicates a possible pathology.

To date, the method of determining basal temperature is recognized as a fairly reliable method for identifying various processes in the body.

By following all the data collection rules, a woman can get a true result with a high degree of probability. This will help her gynecologist to quickly draw conclusions about her state of health and, if necessary, take timely measures to prevent the development of pathology.

How is basal body temperature different from normal body temperature? What indicators of BT and TT are considered the norm? Does basal body temperature depend on body temperature? Below you will find answers to these questions.

What is the difference between basal temperature and body temperature

Basal body temperature (BT) helps to track the various changes that occur in a woman's body. With its help, the presence of ovulation is determined, which allows you to calculate the most favorable days for conception. In addition, BT notifies you of the onset of pregnancy.

Deviation of BT readings from the norm in most cases indicates pathologies in female body. If the basal temperature is uncharacteristic for a particular period of the cycle, you should consult a doctor.

Basal body temperature (BT) and body temperature (BT) are different, the difference lies both in the measurement features and directly in the readings. BT is the resting temperature. It should be measured when you are affected by a minimum of factors, that is, in the morning, immediately after sleep. You can find out the exact basal temperature when the measurements were taken before any physical activity. It is recommended to take measurements before you get out of bed. BBT is not measured during the day, the data obtained will be incorrect, and it is impossible to judge the processes taking place in the female body from them. BBT can be measured orally, vaginally, rectally. When planning conception, to determine pathologies reproductive organs or early detection of pregnancy is important accurate readings, so preference should be given to rectal measurement, in which the error is minimal.

Body temperature can be measured throughout the day, a deviation from the norm can occur both due to health problems and other factors: overheating in the sun, excessive physical exertion, stress, etc. TT displays general degree heating of the body (by internal organs, energy from movement, etc.), while BT indicates the degree of heating of the body only by internal organs, that is, without additional heat produced from the work of the muscles. Basal temperature reflects the real picture of what is happening in the body, so they rely on it when planning pregnancy and at first after fertilization.

Basal temperature can be higher or lower than body temperature, it all depends on the phase of the cycle, so before you start keeping a BT schedule, you should familiarize yourself with the norms. The average temperature of the mucous membranes is 37 degrees and above, while the temperature measured in armpit, is considered normal at an indicator of 36.6.

Does basal body temperature depend on body temperature?

Does it affect basal body temperature? normal temperature body? The pattern between them can indeed be traced. If the TT is increased, then the BT readings will be high. If body temperature indicates a problem in the body as a whole, then this, as a rule, affects both the course of the cycle and the formation of the egg. For example, with colds, TT increases, which, in turn, affects the readings of BT, that is, measurements of basal temperature during ARVI will be incorrect. Since basal temperature in most cases depends on body temperature, gynecologists do not recommend measuring it during any diseases accompanied by elevated temperature. It makes no sense to draw up a graph, analyze it, judge the nature of BT when the body temperature is elevated. It is worth measuring BT only when TT is normal: in this case, the readings will reflect the real picture, which is very important when planning a pregnancy.

During the rise in temperature, it is slowed down. Problems with estrogens lead to violations of other hormones, which is a consequence of elevated temperature and in. Getting pregnant with such a schedule is extremely problematic - treatment is required.

REFERENCE! With a lack of estrogen, menstruation may come with the same frequency. The absence of obvious symptoms of the disease prevents a woman from detecting it.

A similar schedule can be observed in the inflammatory process, when estrogens are normal.

With inflammation of the ovaries

Schedule in the inflammatory process looks pretty specific. It is characterized by intense temperature jumps. They can be seen in the first half of the menstrual cycle. The indicators reach the mark of 37 degrees, and remain at this level for several days.

Then comes sudden drop in temperature. A woman can confuse such a phenomenon with. To prevent this from happening, it is recommended to analyze the schedule in conjunction with an ultrasound examination.

IMPORTANT! In the presence of inflammatory process there is a change vaginal secretions, appearance pain in the lower abdomen and back.

With estrogen-progesterone deficiency

In case of shortage at the same time two important hormones: estrogen and progesterone, there is a slight increase in temperature (by 0.1–0.3 ° C), and the output also has a mild rise in indicators.

If you have such a schedule, you should visit a gynecologist. After the examination, the specialist will prescribe the appropriate treatment aimed at restoration of hormonal levels.

With insufficiency of the corpus luteum

After the incident begins to act, it is also called phase corpus luteum , which is formed at the site of a burst follicle and produces progesterone, the hormone of pregnancy. Its main function is to prepare for implantation and is also responsible for support. Its deficiency affects reproductive function.

Previously, it was thought that possible pregnancy ovulation or gynecological disease possible only after passing a huge number of tests.

Today, such a myth will help dispel a simple basal temperature chart that any woman can independently draw up. He will not give an exact answer, like a doctor, but he will show him and you what is happening with the female body. This article will provide basal temperature charts with examples and transcripts, as well as what basal temperature is for and what it means.

• when you can not get pregnant for many months;
• risk of possible infertility;
• hormonal disorders.

In addition, measuring BBT helps increase the chances of successful conception and the ability to plan the sex of the child. A template or sample basal temperature chart can be downloaded online.

Many women do not take the measurement of basal temperature seriously, believing that this is a mere formality that is of no use. However, this is not the case. Thanks to the indications of BT, the doctor can determine the following points:

• establish how the maturation of the egg takes place;
• determine the ovulatory period;
• approximate date of the next menstruation;
• not infrequently, according to the indications of BT, it is possible to determine a possible endometritis.

It is necessary to measure BT within 3 cycles, this will give more accurate information about the date favorable conception. An experienced gynecologist will help decipher the readings of the graph. Also, an example of basal temperature charts can be seen on the Internet online.

BBT thermometer

For measurement, one type of thermometer is used; during the measurement, it is not changed. Thus, it will be possible to see the norm or deviations on the basal temperature chart.

A mercury thermometer measures the temperature within 4-5 minutes, and an electronic one is 2 times faster. Do not forget to wipe the device with an antiseptic before and after each measurement and allow it to dry before use.

Correct BBT measurement

Accurate and efficient scheduling requires compliance with certain rules:

• measurement of BT should be daily, if possible and during menstruation or at the time of a respiratory illness;
• temperature measurements are carried out in the rectum, in the mouth or in the vagina. The main rule is that the place of measurement does not change throughout the cycle. Doctors still strongly recommend measuring the vaginal temperature. If BBT is measured rectally or vaginally, then narrow part the device is carefully inserted into the required place for 3-4 minutes;
• you need to measure BT immediately in the morning after waking up without getting up, this is a strict rule, moreover, at the same time. Measuring basal temperature an hour after sleep or during the day may not give accurate results;
• measurement is carried out only in the supine position. Therefore, you will need to prepare your thermometer in the evening and put it next to the bed. If you need to go to the toilet, then you will also have to endure a couple of minutes. Excessive activity will give an unreliable result;
• after measuring BBT, readings are taken immediately. If this was done after 2-5 minutes, then the result is considered invalid;
• keep in mind that intimate relationships in the evening or in the morning, as well as flights, too active sports and colds may incorrectly affect the correctness of the basal temperature result;
• BT should also be measured after 4 hours of uninterrupted sleep.

BT information table

The table for determining BT should include the following items:

• day of the month, year;
• cycle day;
• measurement result;
• additionally: here you need to specify all the parameters that can affect the BT. These include: vaginal discharge, having sex the day before, manifestation allergic reactions, viral disease, reception medications etc.

A detailed description of these factors will help the doctor most accurately determine the time of conception. If desired, the basal temperature chart can be downloaded from any medical site related to gynecology.

BBT changes relative to the cycle

Note that BT changes depending on the cycle, or rather its time.

So, in the first phase of the cycle, when only the maturation of the egg occurs, BT is low, gradually dropping to a minimum, then it goes up again. The difference between the highest and lowest BT is from 04 to 0.8 degrees.

If measurements are taken at the time of menstruation, then the temperature will be exactly 37 degrees, and after the end of ovulation, it rises to 37.-1-37.1 under the influence of progesterone.

If the graph showed that BBT in the first phase is much higher than in the second, then there is a clear lack of estrogen. Might need an appointment hormonal drugs. In the case when the second phase is characterized by a low temperature relative to the first, then here in question about low progesterone.

When both cycles are persistent, this indicates ovulation that has occurred. If there is no increase in BBT in the second phase, then, most likely, there was no ovulation, i.e. the egg did not come out.

The BT schedule is quite convenient and modern way determining ovulation, which is an integral part of planning a successful pregnancy. The results of the basal temperature will be useful before going to the gynecologist.

Deciphering and examples of BT charts

When the schedule is built correctly, and the woman followed all the recommendations in compiling it, then it allows not only to determine the presence of ovulation, but also possible pathologies sexual sphere.

On the graph, you can see an overlapping line that is drawn on top of six temperature values, namely in the first phase. This is how a normal basal temperature graph looks like, without pathologies and deviations. We do not take into account only those days where the result could be distorted under the influence of taking drugs, viral diseases, sexual intercourse the day before, etc.

Effects of ovulation

To determine ovulation, you need to use the standard rules:

pay attention to middle line and on 3 results of BT, the difference in two cases out of three should be at least 0.1 degrees. If these are the results in the table, then after 1-2 days it will be possible to observe a clear line of ovulation.

The duration of the second phase

As we found out, the BT chart is divided into two phases, we see this in the photo above, where the vertical line is. The norm of the cycle in the second phase is from 12 to 17 days, but most often 15.

As practice shows, quite often there is a failure in the 2nd phase. If you noted that this phase shorter by 8-10 days, then this serious occasion see a doctor.

If we talk about the norm of BT, then its difference between the first and second phases is about 0.4-0.5 degrees, but no more.

Two-phase cycle and its norm (normal two-phase schedule)

On this graph, it is necessary to note an increase in BT by no more than 0.4 degrees.

If we refer to the example of the chart above, we can see that 2 days before ovulation, BBT decreases.

Hormonal deficiency: progesterone estrogen

With this insufficiency, it will be possible to notice a significantly weak rise in BT, and the difference in the first and second phases will be no more than 0.2 degrees. When similar phenomenon there are more than three cycles in a row, then we can talk about serious hormonal disruptions. As for the pregnancy itself, it can occur, but at the same time there is a high risk of miscarriage.

Also, do not forget about anovulatory cycles. This can happen up to three times a year in a woman's life. However, if the number of such cycles exceeds 3-4, then this is a serious reason to consult a doctor.

You can clearly see the absence of ovulation on the chart below:

Hormonal insufficiency: estrogens

If at the end of the graph, a woman observes large differences in BT, and the line itself is in a chaotic state, then we can talk about a lack of estrogen.

The insufficiency of this hormone can also be seen by an increase in temperature in the second phase to 37.2, sometimes up to 37.3.

Note that the rise in temperature is very slow and can last up to 5 days. In this case, it cannot be said that this basal temperature will be perceived by the doctor as the norm.

The graph below shows how estrogen deficiency manifests itself.

Basal body temperature is the most low temperature inside the body, measured after a long rest. Fluctuations in this temperature reflect the processes that occur in the female body. Measurement of BBT indicators and its fluctuation graph helps to find out the day of ovulation in women and use this information to plan or prevent conception.

The accuracy of determining ovulation will depend on the correct measurement. Consider how to measure the temperature.

BBT should be measured without getting out of bed, immediately after sleep. The main condition is not to make any movements, not to lift vertical position torso, do not stand up. Any movement activates blood flow and increases the temperature inside the body. It is for this reason that the temperature is higher in the evening.

It is required to determine the minimum temperature that is formed only due to the work internal organs. Therefore, it is necessary to measure BT immediately after waking up, before washing and going to the toilet.

The following conditions must be met:

It should be borne in mind that the following factors can affect the temperature indicator:

• lack of sleep;
• disease digestive organs(inflammation of the liver and pancreas, intestinal disorders);
• stress, nervous experiences, mental overload;
• alcohol taken in the evening.

The above factors reduce the effectiveness of the graph, as they violate the rules of measurement.

BBT indicators and measurement technique

The thermometer must be inserted into any open body cavity (anus, vagina, mouth). According to the technique that was developed by Professor Marshal, basal temperature is measured through the anus. This is often done if the temperature needs to be measured in a newborn baby. It is not possible to keep the thermometer under the arm, because it is inserted into the anus.

For women, determining the temperature in the vagina or anus allows you to find out fluctuations in tenths of a degree. It is fractions of degrees that show significant jump in ovulation basal score.

Meaning of measured indicators

The BBT measurement method is designed to determine ovulation. Ovulation is the exit from the shell of the follicle of the egg, which occurs after its maturation. The egg starts to be released fallopian tube and move to the uterus. These changes accompany an increase in temperature by tenths of a degree. BBT before ovulation first decreases slightly, and then increases sharply. Since the release of the egg, conception is possible.

Daily temperature measurement makes it possible to know the day of ovulation. This, in turn, allows you to take appropriate measures to prevent pregnancy or, conversely, to try to get pregnant on these days.

BT chart

The measured indicators are entered into a table and begin to keep a graph. In addition, the table should include additional factors, affecting measurement accuracy(presence of headache, infection, cold).

The graph looks like a broken line. At the beginning of the monthly indicator is approximately at around 36.9-37.1C (fluctuations of 0.1-0.4C are possible).

After menstruation, the degrees decrease to the lowest levels - 36.6-36.9C. This temperature is required for the maturation of the egg. The ripening period can take up to 2 weeks, so in the next decade the graph will begin to fluctuate around one indicator - from 36.7C, down or up by 0.1-0.3C.

The day before ovulation, the degree decreases (by 0.3-0.5), then sharply increases by 0.4-0.7C and reaches 37C.

temperature during ovulation

BBT during ovulation is a slight decrease before increasing to 37C. By the way, the highest probability of conception on this day is 35%. Therefore, if you are not planning a pregnancy, then you need to limit sexual intercourse or use protection (a condom or other contraception).

After ovulation, basal body temperature is e rise to top level ( with slight fluctuations at the top of the graph).

The subsequent schedule will depend on whether the body is preparing for menstruation or pregnancy has occurred. If pregnancy has taken place, then basal rate will be at a high level. In the female body, progesterone is produced, which maintains a high temperature.

If conception did not occur, then hormonal background normalizes and goes down. This is noted a week before menstruation (BT decreases by 0.4-0.7C).

This ovulation BBT schedule is usually found in healthy women. With some violations, the normal broken graphics get lost, the jump becomes not so pronounced. Then biological method contraception is ineffective. Pregnancy can occur despite the pronounced absence of a temperature jump.

Diagnosis of diseases by BT

The whole cycle of changes during the month makes it possible to identify the causes of infertility and other disorders. most common cause Infertility in women is considered to be the absence of ovulation. Temperature measurement makes it possible to determine which days of the cycle are easiest to get pregnant and whether the release of the egg begins.

In addition, BT indicates the presence inflammatory process in other organs and systems. This affordable way It helps completely free of charge, independently and simply to examine oneself to identify hidden diseases.

Days of desired conception and safe sex

Monthly measurements of BBT make it possible to determine a typical graph of temperature changes in the body. Scheduled from highly likely it is possible to predict the days when pregnancy is possible and the days when conception is impossible under any circumstances. This data can be used as a warning of pregnancy, or to conceive a child. Consider when conception is possible and how to use this method as a contraceptive.

days possible conception- this is two days immediately after the release of the egg from the follicle. And also 2-3 days before the start of ovulation.

These days, the egg cannot yet be fertilized. However, spermatozoa remain viable for several days. Therefore, getting into the uterus through the vagina, they stay in it for 2-3 days and fertilize the egg immediately when it leaves the follicle. That is, a few days before ovulation can be added to the days of probable conception.

The time of ovulation, as well as the days before it (about 4-6 days) are called fetal. If you are not planning a pregnancy, then it is better to refrain from sex. If you have planned a child, then you need to have sex the day before ovulation. How to find out about the release of the egg, which BT should be measured in the vagina during ovulation?

The day of ovulation according to the schedule is a slight decrease in temperature, and after a few days - sudden jump up. These two days must be considered fertile (who wants to get pregnant) or "dangerous" (for opponents of conception).

The time after ovulation is called absolute infertility. The life span of an egg after release is one day. And. unfertilized egg after this is destroyed, the possibility of becoming pregnant after ovulation after two days is minimal.

The above division of days into periods of impossible and possible conception is not fair for all women. The protection system will only work if the menstruation is stable. For others, this method is ineffective.

Deviations and the norm

Any changes in the BBT indicator are the result of hormonal disorder. In a woman's body, all vital processes are determined by hormonal changes. Therefore, pregnancy occurs due to changes in BBT.

During pregnancy, BT is at a high level (more than 37.3C). The presence of increased BBT creates the hormone progesterone, which is intensively formed in the first 4 months of gestation. Therefore, the BT indicator is high at this time. After the amount of progesterone decreases, at the same time B.T. decreases. Therefore, after three weeks of pregnancy, it is pointless to measure its value.

In the first term of pregnancy, BT is the main sign, by which conception is judged even before the delay of menstruation. But this is an ambiguous sign. Preservation high level temperatures may accompany the use of some medicines, physical exercise, inflammatory diseases. Therefore, a test can definitely tell you about pregnancy. And high BT - indirectly.

Definition of pregnancy with BT

Attention should be focused on two main conditions:

1. BBT is measured at the same time in the morning (a difference of no more than 20 minutes is acceptable).
2. BT is measured without getting out of bed. In order to measure the temperature correctly, the thermometer must be left on a table near the bed, where it can be reached by hand, without turning the torso.

You don't need to take your temperature throughout the day. BT during the day will not be able to show important changes in the body. Only daily measurements in the morning will reflect the real level of hormones.

Graph of the basal temperature of a healthy woman during pregnancy

The BBT chart during pregnancy looks like a broken line, fluctuating in the range of + 37.5C. A decrease in the indicator by less than 36.9C indicates that the progesterone content has decreased in the body. This means the likelihood of a miscarriage, a missed pregnancy, or a threat of a breakdown. A doctor's consultation is required.

But this diagnosis is also ambiguous. Probably, you have heard enough stories about difficult childbirth or overwork has affected. Any experiences, overloads and stresses reduce the BT indicator and lower hormone levels. Try to just bounce back and leave your nerves for later.

The maximum value of BT during pregnancy can reach up to + 38C. If your BBT level is higher, you should consult your doctor. This indicator is often accompanied by inflammation, internal infections.

What should be BT before menstruation? And why is this indicator important? Temperature measurement before and during menstruation makes it possible to determine the presence of an inflammation process in the body. If the temperature during menstruation jumps above 38C, then this means that there is a hidden source of inflammatory disease inside.

1. BT before menstruation - high. During menstruation, the amount of progesterone decreases, therefore, a decrease in the basal rate begins. From higher rates (37.8C on the first day of menstruation), it decreases to 37.1C (by the 4th-5th day of menstruation).
2. BT during menstruation is the average between the elevated temperature of the previous period and reduced rate after menses. During menstruation, BBT remains at a level of approximately 37C or slightly lower.
3. BT after menstruation is the lowest indicator of the cycle (except for the day of ovulation, when the indicator additionally decreases by several degrees).

Why is it necessary to know which BT is before menstruation? Measurements are required for early diagnosing pregnancy. If you have had sexual intercourse without a contraceptive, then you will be able to detect the presence of pregnancy even before the delay in menstruation. Why measure B.T. If the basal rate does not decrease, then it means that there is a pregnancy.

If you follow all the rules for determining the basal temperature, you can discover a lot of new things for yourself. But do not forget that you should not draw certain conclusions yourself, taking into account the obtained graphs. This can only be done by a qualified gynecologist and only after additional examinations.
