The time of the first menstruation after a medical abortion is about 1 month after the medical abortion. The amount of menstruation should be the same as the usual amount of menstruation. If the amount of menstruation is too little or too much, it is normal if it clears normally in 3-5 days. The endocrine secretion will be affected after the medical abortion, so the amount of menstruation may decrease or increase, but if it clears normally, it can be left alone for a while. The first time you get your period after a medical abortion, you should pay attention to keeping warm, avoid getting cold, not eating cold, spicy and stimulating food, and pay attention to keeping your vulva clean and hygienic. If you still have a period more than 40 days after a medical abortion, if you do not take contraceptive measures, you can not exclude the possibility of pregnancy, so we recommend that you go to the hospital for relevant examinations and symptomatic treatment.
