In general, menstruation occurs about 1-2 months after induction of labor, with some individual differences. Induced labor is the process of terminating a pregnancy after 12 weeks of gestation. If the menstrual cycle is regular and the drainage is clean, ovulation can be resumed in about a month, i.e. 1-2 months for menstruation. If you do not have a period for two months, you need to perform an early pregnancy test to rule out the possibility of another pregnancy, and there are also factors such as endometrial damage after induction of labor and uterine adhesions, etc. It is recommended to go to the hospital in time for examination to rule out pathological causes and observe for a period of time. Ovulation can also be delayed due to drugs or environmental influences, and there are very few late induced abortions due to poor return of milk, which can also lead to delayed menstruation. If you have irregular menstruation before induction and the time of menstruation cannot be estimated, you need to go to the hospital to check ultrasound and hormone level if necessary to treat related diseases and increase the chance of next pregnancy. In addition, since there is no menstruation, it is still necessary to take safe contraceptive measures during intercourse to avoid another pregnancy in a short period of time.
