How to calculate ovulation?

The female menstrual cycle is usually determined by the growth and maturation time of egg cells, and the female menstrual cycle is affected by the periodic secretion of hormones by the ovaries. Therefore, the relationship between a woman's menstrual cycle and the cyclic secretion of hormones from the ovaries is the woman's ovulation period.

A woman's ovulation period usually occurs about 14 days before her next menstrual period. To more accurately calculate a woman’s ovulation period, we can use the following formula:

14 days before the next menstruation is the ovulation period for women

For example, if a woman's menstrual cycle is 28 days, then October 23rd would be 14 days before her next period. Therefore, a woman’s ovulation period is 14 days before October 23, that is, October 18.

In addition to using formulas, there are other ways to more accurately calculate a woman's ovulation period. For example, women can predict ovulation by observing changes in their sexual desire. Generally speaking, during women's ovulation period, they experience increased sexual desire and may feel more sensitive and aroused. In addition, women can also predict ovulation by measuring their body temperature. Generally speaking, during women's ovulation period, their body temperature will rise by about 0.3-0.5 degrees Celsius.

To sum up, by using formulas and observing sexual desire, body temperature and other methods, women can more accurately calculate their ovulation period and take corresponding measures to increase their chances of pregnancy.
