Generally, the ovaries can regain their ovulation function about 22 days after an abortion, and menstruation usually resumes around 1 month after the procedure. However, for some individuals, there may be a delay of a few days, and it is considered normal for menstruation to return within 40 days.
The timing of menstruation after an abortion varies depending on the gestational age. In general, for early pregnancies, menstruation typically resumes in the second menstrual cycle following the abortion. However, due to individual differences in physical condition and the trauma to the endometrium caused by the abortion, it may take a longer time for recovery. Some women may also experience menstrual irregularities due to complications from the abortion procedure. Additionally, hormonal changes caused by the abortion may result in a delay in ovulation and subsequently a delay in menstruation. Therefore, it is recommended to seek a detailed examination at a hospital if menstruation does not resume after an abortion or for several months.
