Calculating the days of ovulation.

If a woman has a normal menstrual cycle lasting 28 days, she usually ovulates on the 14th day. How to calculate the day of ovulation? There is one available way - by measuring rectal temperature (that is, the temperature in the rectum). This is done like this: every day in the morning, without getting out of bed, a thermometer is inserted into the rectum for 3 minutes. The temperature is then recorded, charting its fluctuations throughout the menstrual cycle.

Starting from the first day of the next menstruation and until the 14th day, the rectal temperature should be below 37 degrees. On the day of ovulation it is also below 37, but from the 15th day it begins to rise and remains for almost two weeks at a level above 37 degrees, falling before menstruation. Accordingly, if the temperature has increased since the 15th day, then ovulation took place the day before. Moreover, the difference between the first and second half of the cycle should be no less than 0.6-0.8 degrees. For more accurate results, be patient and measure your temperature every day

For 3-4 cycles. And when a woman, after such a long check, sees from the charts that ovulation occurs each time clearly on the 14th day of the cycle (or, perhaps, clearly on the 15th) and there are no shifts, she can be sure that this method suits her.

The most dangerous period is from the 10th to approximately the 19th day from the beginning of the menstrual cycle (that is, the day of ovulation itself, five days before it and three days after). And the safest period, respectively, is until the 10th day from the start of the cycle and from the 20th to the 28th day.
