Method for measuring and tracking the level of BT with scheduling allows you to monitor fertile days favorable for conception. This method is quite common, they are successfully used by many women when planning a pregnancy to monitor the overall health. The basal temperature during conception until it is different. Due to the easy and intuitive graph, you can easily determine when to begin menstruation, there are problems with hormonal level, there is a threat to the unborn child. Measurements are made on a specific, well-made plan, all the data are entered into a special surveillance list.

Basal temperature - what is it?

What is BT or basal temperature? This thermometer readings that are obtained rectally, vaginally or orally after sleep. The temperature level is constantly changing. With the schedule can be easily understood when the egg matures, which days are most favorable for conception. The first phase is called the follicular, it lasts from the end of menstruation and before ovulation. At this time in the body is dominated by estrogens. Level BT kept at 36-36, 5 degrees. The duration of different phases of - 10 to 20 days.

The most favorable time for conception is the 3-4 days before ovulation.

At this time, the egg may merge with sperm, and then begin the formation and development of the embryo. The second is called luteal phase in this period is dominated by progesterone. At the site of the ruptured follicle forms the corpus luteum. Duration - 12-16 days, the temperature is kept at 37 degrees. The third phase develops when conception occurred, it can keep track of 14 days, after which the data is not so reliable.

Terms of the basal body temperature

For schedule of basal temperature was drawn up correctly, it is necessary to ensure measurements WT properly. For this there are special guidelines to help make things right:

  • BT need to measure every day, including the days of menstruation;
  • WT can measure the level, not only in rectum but also in the vagina, mouth. Under his arm should not be measured, as readings will be incorrect. Measuring time - 3-5 minutes;
  • BT need to start measuring immediately after waking up, before a meal, do not get up;
  • to get the result you must choose a specific time, closely follow this condition. It must be remembered that every hour of sleep increases the level at 0, 1 degree;
  • before measurements sleep duration should be at least 3-4 hours. Before that, you can not get up, go to the toilet;
  • a thermometer to measure you want to use one and the same, as may be significant differences;
  • it is necessary to lie down during the procedure, it is not recommended to sit, roll over, as it raises the level of BT;
  • readings should be recorded immediately after the measurement;
  • should be fixed in the schedule of monitoring all developments relating to illness, increase or decrease in blood pressure;
  • WT display level during infectious diseases involving temperature should not, they do not carry useful information.

What should be the basal temperature during pregnancy?

Basal body temperature during pregnancy immediately changed. It's pretty easy to determine without a specialist. Additional characteristic features should be noted:

  • 5-7 days after ovulation, decrease of temperature to 0, 3-0, 5 degrees. This so-called retraction of the implantation, when the embryo is attempting to infiltrate the endometrial tissue of the uterus. That is, he is looking for a suitable place for himself where he will develop further. During this period, for 1-2 days may be a little bleeding, which is also called implantation. The color of this bleeding bright red, but rather a light brown, creamy;
  • in the second phase the temperature rises, its level is 37 degrees;
  • before the expected date of menstruation did not show the characteristic temperature drop, on the contrary, its level increased by 0, 2-0, 3. In the graph it is released the third phase;
  • menstruation does not occur, there is high temperature, retained at the same level for about 16 days. At this time, it is necessary to make the first pregnancy test;
  • the schedule may not necessarily be similar to the classic, every body is individual, so the symptoms of pregnancy can also be very different. If there is a chance of pregnancy, it is best to consult a gynecologist.

There are some points that must be observed at the very beginning of pregnancy by measuring the basal temperature. The first couple of weeks, we need to continue to measure BT, as these data can be very important. Factors that need to pay attention to the following:

  • WT level should be above 37 degrees when the temperature has dropped in the first two weeks, then it means that the embryo is compromised. Most often, this lack of progesterone, you should consult a doctor to make US;
  • If BT is raised higher than 38 degrees, it is also quite formidable sign, indicates the presence of infection, inflammation. If such an increase were single and never repeats itself, then do not worry. If the temperature does not drop, it is not worth waiting, you must immediately make an appointment with a gynecologist;
  • after 14 days the level of BT can not be measured, since the indications are implausible, aided by ever-changing hormones.

Lowering and raising the temperature level

The graphs of basal temperature should contain the following lines:

  • month, day of the month;
  • day cycle;
  • BT;
  • Notes (deviations, plentiful or scanty allocation, fever, stress, intake of sleeping pills and other drugs, sleep late, etc.).

Only the proper management of this schedule will allow the doctor to make conclusions about the state of health. The ideal schedule of BT should contain a line similar to the flying bird, whose wings spread out to the sides. The difference is between 0 and 4 degrees, the line should not be smooth or chaotic. Low and high temperatures indicate the processes occurring in the body. Rapid changes may suggest possible violations in the body.

The high temperature in the first phase of the schedule may be indicative of such violations:

  • lack of estrogen. The temperature at this time should oscillate at 36, 2-36, 5 degrees. When she got up, it indicates that the allowable level of estrogen decreased. With an average temperature at 36, 5-36, 8 degrees are appointed by hormones;
  • increase in the second phase from 37, 1 degree, which lasts more than three days. This is a sign of hormonal disorders require medical consultation;
  • inflammation of the appendages. Symptoms of the disease - the temperature rise in the first stage to 37 degrees, usually it lasts for several days. Gradually, it is reduced, but it is very difficult to calculate ovulation.

Lowering the temperature indicates that the observed hormonal disturbance, corpus luteum formation processes are complicated. If any violations of the temperature chart that repeat, it is necessary to contact a specialist. This is particularly important at the beginning of pregnancy, when the smallest failures can cause degradation and negatively impact on the fetus.

What can you learn from the testimony of basal body temperature?

In the measurement of basal body temperature can be obtained many data including hormonal background, the presence of certain diseases, disorders, and how well the overall cycle proceeds. The normal schedule between the first and second phase difference information indicates the average of 0 and 4 degrees. If it is lower, it is a sign of hormonal problems. It is recommended to donate blood to check the level of estrogen, progesterone, contact your gynecologist. Increase in basal temperature observed when progesterone levels is 2, 4-4 ng / ml.

All the classic guide to deciphering the basal body temperature charts describe several key provisions of the curve on the graph, each of which determines the general condition.

  1. Normal cycle notes biphasic increase in the second phase to a value between 0 and 4 degrees observed decline before menstruation. After ovulation, increases the duration of not more than 12-14 days.
  2. Hormone deficiency appears bland temperature rise at 0, 2-0, 3 degrees. If such graphics repeated from cycle to cycle, you should immediately consult your doctor, as a sign of infertility provoked by hormonal deficiency. Increase can be observed just before menstruation, and the necessary reduction before it is absent. The second phase lasts up to 10 days. Pregnancy in some cases may occur, but it is under threat from the outset. Sometimes doctors do not give a verdict of infertility and miscarriage. If this schedule is repeated more than three times in a row, it is necessary to consult the doctor, since the beginning of the pregnancy is already a problem.
  3. Anovulatory cycles occur about once a year in any woman. If it is not repeated often, no cause for concern. In a series of missing the point of ovulation, if the schedule is constantly repeated, this indicates sterility, should consult a specialist.
  4. Estrogen deficiency is shown as a chaotic irregular curve that shows no signs of any of the types listed. It occurs most often in hormonal disorders, but the impact may have and other factors.

What affects the basal body temperature change?

In the measurement of basal body temperature during pregnancy is important to remember that some factors have a certain influence on it. Among such factors should be noted:

  • exercise, even the most insignificant. Therefore, it is recommended to measure the temperature in the morning immediately after waking up. Lying should be quiet until the process is complete;
  • when measuring the need to take a horizontal position. You can not sit down, because in this position to the pelvic organs will increase the blood flow, and this will make incorrect readings;
  • sleep should be a continuous minimum of 4 hours. If the dream was short, the evidence will be false;
  • you can not have sex just before metering. If a schedule of basal temperature, you have to completely abandon the time of sexual activity, only one can be sure that all the data is correct. In an extreme case we needed a break for at least 12 hours before, how to measure basal temperature;
  • immediately after waking can not eat, because it has a negative impact on the data. Even for pregnant women who suffer from toxemia, it is necessary to be patient;
  • receiving medications may cause an increase or decrease in temperature. At the time schedule is necessary to refuse to accept even drugs for headaches, because they distort the picture, the doctor can not correctly decode the schedule;
  • colds, infectious diseases. A schedule under these conditions does not make sense. For pregnant even a slight cold - is a serious reason to see a doctor, to postpone the visit should not be.

It must be remembered that the basal temperature during pregnancy is not reliable at all times, but only the first two weeks. Already in the third week of hormones varies greatly, indications are distorted and become completely useless.

Basal temperature allows to learn a lot about the state of the body, but the scheduling is necessary to strictly adhere to the rules of such data. Small deviations from the instructions just turn your work into a useless waste of time.
