Calculating the safe period and ovulation period is very important for many women because these two periods are important periods for pregnancy. However, how to calculate the safe period and ovulation period is a more complicated issue. In this article, we will introduce some methods of calculating safe period and ovulation period.

Next, we will introduce some commonly used calculation methods. The first method is to use the calendar method. This method divides a woman's menstrual cycle into 12 phases, each phase lasting 14 days. On the 14th day of the female cycle, which is the female's ovulation period, the egg will be released from the female body. In addition, the 13th and 15th days of the female cycle are also safe periods for women.

The second method is to use the basal body temperature method. This method is to record the woman's basal body temperature in a table and analyze changes in body temperature. Typically, a woman's basal body temperature begins to rise on day 14 of the cycle and reaches its peak on day 21 of the cycle. In addition, the 13th and 15th days of the female cycle are also safe periods for women.

The third method is to use the test strip method. This method involves inserting a test strip into a woman's urine and observing the test results from the test strip. Typically, women begin testing on day 14 of their cycle and end on day 21 of their cycle. In addition, the 13th and 15th days of the female cycle are also safe periods for women.
