It is easy to get pregnant after menstruation, mainly because the endometrium enters the proliferative phase after menstruation, and then gradually thickens and enters the ovulation phase. The thickness of the endometrium is suitable for the fertilization of the egg after ovulation, so the chance of pregnancy is clinically very high at this time. If you are planning to get pregnant, it is recommended to calculate the ovulation period according to your ovulation time, and to schedule your sexual intercourse reasonably during the ovulation period, which will increase the chance of pregnancy. If you are not planning to get pregnant, it is recommended that you take contraceptive measures when you have sex during ovulation or take oral emergency contraceptive pills within 72 hours after sex, so as to avoid the possibility of pregnancy. In addition, it is recommended to pay attention to hygiene during sex to avoid inflammatory reactions in the reproductive tract.
