If the menstrual cycle is normal, the day of ovulation is 14 days before the next menstrual period, and the 3 days before and after the day of ovulation are the danger period, except for the danger period, which is the safe period.
Everyone’s safety period is different, and it is closely related to the individual’s menstrual cycle. The safe period is not absolutely safe. Do not think that you can use other contraceptive measures during the safe period. If you want to use safe period contraception, you must first accurately determine the ovulation period. For women with a 28-day menstrual cycle and a regular cycle, ovulation occurs 14 days before the onset of menstruation. It is possible to get pregnant if you have intercourse 3 days before or after ovulation. The 5 days before and 3 days after menstruation can be called the safe period. Judging the safety period only reduces the chance of pregnancy and is not a method of contraception. For women with irregular menstrual cycles, it is not possible to use this to determine the safe period. Since the cycle is irregular, ovulation is not regular and it is not possible to determine the day of ovulation. It is advisable to choose ovulation test, basal body temperature test or cervical mucus monitoring to determine if you are ovulating. As long as you are not ovulating, it is relatively safe.
However, the safe period is only relatively safe, if you do not want to get pregnant, contraceptive measures should still be done.
