For women with regular periods, the day of ovulation is usually about 14 days before the onset of menstruation, and the five days before and four days after the day of ovulation are known as the ovulation period, while the safe period is usually the time outside the ovulation period.
The average regular woman has a menstrual cycle of about 28 days. Ovulation usually occurs on the 14th day before the onset of menstruation, and the 5 days before and 4 days after the day of ovulation are the ovulation period, which can last for 2 to 3 days. Ovulation can last for 2-3 days. During this period, ovarian ovulation is more likely, and women have a higher probability of getting pregnant during intercourse.
The safe period is usually the non-ovulatory period. During the non-ovulatory period, since no egg cells are discharged from the woman’s body, she will not get pregnant even if she does not take contraceptive measures. During menstruation, due to the opening of the woman’s cervix, intercourse is not recommended even if there is no ovulation, otherwise it may lead to infection in the uterine cavity.
However, for women with irregular periods, the calculation of ovulation and safe period may be a little different. Both women with regular menstruation and women with irregular menstruation who have no plans to have children are advised to still take solid contraceptive measures during the safe period to prevent unwanted pregnancies from occurring.
