In general, menstruation will occur about 1 month after the abortion. For women who have regular menstruation in their daily life, the recovery of ovulation after abortion is usually about 20 days after the procedure, and the onset of menstruation should be about 1 month according to ovulation. However, some women may delay the onset of menstruation if their endocrine recovery is slow. Therefore, if you have not had your period for more than 40 days after the abortion, you should go to the hospital for a review. To determine whether the absence of menstruation is due to delayed ovulation, poor recovery of the uterus, or adhesions in the uterine cavity, the cause should be clarified and treated accordingly. In addition, after the abortion, patients should pay attention to keep warm, drink warm water, and eat some red dates and red beans to replenish blood.
