Ovulation is the process by which egg cells are expelled along with surrounding cumulus granulosa cells. A woman's ovulation date is generally about 14 days before her next menstrual period. Eggs can survive in the fallopian tubes for 1-2 days after being released from the ovaries.

The formula for calculating ovulation is:

First day of ovulation = number of days of the shortest menstrual cycle minus 18 days;

Last day of ovulation = number of days of the longest menstrual cycle minus 11 days.

For example, if the shortest menstrual period is 28 days and the longest is 37 days, it is necessary to subtract 18 (28 18 = 10) from the shortest regular period and 11 (37 11 = 26) from the longest regular period, so the 10th to 26th days after menstrual cramp are ovulation periods.

You can go to the pharmacy and buy a test strip to test it.

Analysis of the uproar of illness and defeat:

The safe period refers to the regular menstrual cycle of women, between the two menstrual periods, in addition to the time of ovulation and menstruation, because the probability of conception is low, so it is called the safe period

Generally, one week after menstruation is clean and one week before menstruation, but some people may also ovulate during the safe period, so contraception during the safe period is unreliable and unsafe. The rest of the time is a dangerous period! Easy to get pregnant!
