Vaginal bleeding after abortion usually lasts 7-10 days, up to 14 days, more than 14 days of bleeding is abnormal. Therefore, if there is brown discharge after abortion, if it occurs within 14 days, it belongs to the normal range. If there is still brown discharge after 14 days, it is a small amount of bleeding, and you must go to the hospital to do the examination, and the examination is as follows: firstly, take blood test for chorionic gonadotropin (HCG) as an indicator to determine if there is any residue; secondly, do vaginal ultrasound to look at the situation of the uterine cavity, and see if there is any residual tissue, and if there is any high echogenicity. If there is residue in the uterine cavity or HCG is still high, this is considered an incomplete abortion, need to use medication, and if necessary, need to clear the uterus again. If HCG, that is, chorionic gonadotropin is normal, there is no residue in the uterine cavity, and there is still brown secretion, then it is considered that the uterus is not well restored, and the addition of medicines to promote the uterine contraction can be done, and it’s not a big problem.
