A few days before menstruation comes is safe period

In general, the first few days of menstruation belong to the safe period. The middle period of two menstrual periods is the ovulation period, two weeks or 10 days before and after the ovulation period is the fertile period, and other times are relatively safe periods. Therefore, generally speaking, the first week of menstruation and the week before menstruation belong to the relatively safe period. The first few days before menstruation are generally within the safe period. However, during the safe period, other contraceptive methods should also be used, because there may be ovulation in advance or delayed. The general safety period should be combined with condoms or morning-after contraceptives to improve the contraceptive effect.
