Ovulation does not occur during menstruation. A woman’s menstrual period and ovulation do not occur at the same time. If a woman has a regular menstrual cycle of 28-30 days, the day of ovulation is 14 days before the next menstrual period, 5 days before and 4 days after the day of ovulation. Conception occurs easily when sex occurs during ovulation, and contraception is needed if there are no plans to have children. Although women do not ovulate during menstruation, they should not have sex either. When a woman is menstruating, her cervix is in an open state, so if she has sex, it is easy to cause an upward infection, leading to gynecological inflammatory diseases, which is extremely unfavorable to the woman’s body. If you want to get pregnant, you need to have sex during the ovulation period.
