Basal temperature in the second phase

Such an indicator as the basal temperature, in the second phase of the female cycle has a special informativeness. In this case, the division into phases on the graph occurs exactly in the place where the ovulation line is located.

How does the basal temperature change in the second phase?

In the absence of diseases and disorders of the reproductive system, the basal temperature is in the range of 36.4-36.6. In the second phase, it rises and is at the level of 37 degrees. In those cases where the temperature difference between the phases of the cycle is less than 0.3-0.4 degrees and the average index of the second phase reaches a value of 36.8, they indicate a violation.

What is the increase in basal temperature?

Normally, every time, just before ovulation (12-14 day cycle), the basal temperature rises. This physiological process is caused by the formation of a yellow body, which produces a hormone progesterone, which increases the temperature values. When pregnancy does not occur, it stops working and the temperature drops. In those cases when the hormone is produced in insufficient volume, the temperature does not rise, and then they talk about the deficiency of the yellow body.

When there is a decrease in basal temperature?

In some cases, women who are just starting to plot a basal temperature schedule are interested in what it is after ovulation.

As is known, in the norm, at the moment of ovulation the temperature indicator becomes equal to 37 degrees. If fertilization does not occur within 6 days of ovulation, the temperature decreases. So, the normal basal temperature before the monthly is 36,4-36,6 degrees.

In some cases, there is no reduction. Then the basal temperature in the second phase of the cycle, after the last ovulatory process, remains at 37 degrees. Most often, the reason for this is the pregnancy that has come.
