The basal temperature after ovulation can become very informative if you have a regular cycle and you are measuring correctly. At first glance, this seems like a futile exercise - measuring basal temperature, but in fact this figure allows you to plan your life. To know how to do this, you need to understand the concept of the relationship between basal temperature and the cycle.

What is basal temperature and how to measure it?

Your basal body temperature is your temperature, when you are completely calm and relax. Your basal body temperature varies depending on a number of factors, including your hormones. When ovulation occurs, the hormone progesterone causes a rise in temperature. He remains higher during a two-week wait. Then, shortly before the start of your menstrual period, the hormone progesterone falls. And if you are not pregnant the temperature will drop, because in this case your temperatures will stay higher, because progesterone will remain high.

Thus, the level of hormones determines the temperature fluctuation. It is this oscillation that depends on the different hormonal phases that suggest changes associated with ovulation. Actual temperatures are less important than the designation of a picture showing two temperature levels. Before ovulation occurs, the initial body temperature ranges from 36.1 to 36.3 degrees. This is due to the presence of estrogen, which slows the rate of increase in temperature.

After the release of the egg, the rate rises to a new, higher level, usually ranging from 36.4 to 36.6 ° C. Over the next 24 hours, the temperature usually rises not less than 0.2 degrees, and then continues to increase slightly. This increase in temperature is caused by progesterone released from the follicle after ovulation. In a few days it will become obvious that it is in a new, higher range. The pace itself will continue to grow and fall from day to day, but will remain in a higher range.

Actual temperatures are less important than the designation of a picture showing two temperature levels. If there is no pregnancy, then your temperature will rise for 10 to 16 days, until the yellow body regresses. At this time, progesterone levels drop sharply, and you get your period. Your temperature usually falls and at this time, although it is not uncommon to have unstable or high temperatures during your period.

How to measure the temperature? To build a diagram of your basal temperature, which will allow you to judge about your cycle, then you should, for at least a month, track your temperature and cycle. Start better from the first day and follow daily measurements by recording them. On the first day of the next period, start a new schedule and the recording process again and again. Continue typing the chart for at least 3 cycles, because only so you can know exactly when to expect ovulation.

Take your first temperature in the morning before getting out of bed or even talking - leave your thermometer near the bed within easy reach so you do not have to move much to get it. If you are using a glass thermometer, make sure you shake it before going to bed.

Try to maximize the temperature measurement to the same time each day - set the alarm clock if you need to. Measurement for half an hour in both directions from the average measurement time is the best way to control. After all, your tempo and temperature can vary with time (for example, if you usually measure your temperature at 6 am, it's quite normal to measure it between 5: 30-6: 30, but the closer to 6, the better). The normal variation is up to 0.2 degrees per hour - lower if you measure your temperature early, higher if you are late.

It is best to take measurements after at least 5 hours of sleep.

You can measure your temperature on the mucous, vaginally or rectally - just use the same method for the entire cycle.

You should try to put the thermometer in the same way every day (same location, same depth vaginally and rectally).

Plan your temperature on the graph every day, but refrain from too much prediction until the cycle is complete. After three months of charting, you will get basal body temperature data that accurately displays ovulation and all processes to control your cycle and sex life.

Changes in basal temperature in ovulation

The level of rise or fall of temperature can not predict ovulation - and this is a major nuance. But you can know when exactly it happened and a few days after it happened, thanks to the diagram. Therefore, you can not judge whether you have had sex in the "right days" until ovulation occurs. You, most likely, will become pregnant, if you had sex for two days, preceding ovulation.

What is the basal temperature after the day of ovulation? The norm of this indicator varies, but after ovulation there should be a temperature shift of at least 0.4 degrees during the 48-hour period to indicate ovulation. This shift should be higher than the highest temperatures in the previous six days, allowing one temperature to be thrown out as inaccurate (accident, illness). Perhaps the best way to explain this is to set an example.

For example, if after ovulation the basal temperature of 37-37.4 is a sign that ovulation has occurred. But if the basal temperature after the expected ovulation is 36.6-36.9, then one can expect that there was no ovulation or inaccurate measurements.

After you see a temperature shift for at least three days or at the end of your cycle, you can mark the middle between the follicular phase and the temperature of the luteal phase, which corresponds to ovulation.

Therefore, you should observe an increase of 0.4 - 0.5 degrees higher than the temperatures throughout your entire cycle. If fertilization occurs, progesterone does not decrease and keeps the temperature at a stable level. The basal temperature after ovulation during pregnancy is withheld. This leads to the fact that on your chart there is a period of rising values, which has not been falling for a long time. This may well correspond to pregnancy.

How long does basal temperature last after ovulation? About the 14th day your temperature will rise above the average. This increase occurs within 10-16 days. Your temperature usually falls during 14 days. If this does not happen, it is likely that fertilization has occurred.

For most women, their luteal phase does not change more than a day or two from month to month, even if the length of their menstrual cycle changes. For example, the female cycle may vary between 30 and 35 days, but the luteal phase may be 12 or 13 days. If, after ovulation, the basal temperature does not rise, you need to think about what you do not ovulate. If you do not ovulate, you can not become pregnant. If you irregularly ovulate, this may indicate a possible risk of infertility. The absence of ovulation is called anovulation and is the common cause of female infertility. Most women with anovulation can take medications that will cause ovulation and help them get pregnant.

Sometimes it happens that after ovulation the basal temperature has dropped - this is a sign of impaired regulation of hormones. Perhaps, if you can not get pregnant with this, then you have progesterone deficiency.

High basal temperature after ovulation is a sign of ovulation itself, which for women when planning pregnancy can be an important indicator. But before you focus on regulating your cycle by tracking the basal temperature, you need to build your own chart when you observe at least three months.

It is important to know!

Almost every woman knows about the existence of basal temperature. However, not everyone understands what exactly is talking about, and for what reasons the basal temperature during pregnancy is so variable. Let's try to explain in detail and answer the main questions that are related to this concept. Read more..
