A woman will have her period about 4 weeks after induction of labor. Women usually resume normal ovulation about 22 days after induction and some women resume normal menstruation about 42 days after induction. Irregular menstruation may occur within 3 months after the operation, which is a normal physiological phenomenon and does not need to be treated. Because women will experience a brief period of endocrine disruption after induction of labor, if a woman has not had her period for more than 3 months, she should rule out the possibility of early pregnancy and should have an early pregnancy test. It is also possible that the endometrium of the uterus is severely damaged during the process of induction of labor, which can cause serious damage to the body and mind after induction of labor, and if women have too serious psychological burden or tension, it can also lead to non-menstruation
