Bleeding may occur early after the expulsion of the gestational sac, which is usually normal, and in a few cases it may be caused by incomplete miscarriage. Because after a medication abortion or spontaneous abortion, although the gestational sac has been expelled, the meconium has not been completely shed and needs to be expelled through uterine contractions, and the blood vessels exposed on the surface of the uterus also need some time to recover and close, so there are usually signs of bleeding. Usually, after expulsion of the pregnancy capsule, the bleeding time of medication abortion is longer than that of spontaneous abortion, which is about 7-10 days and up to 2 weeks, while the bleeding symptoms of spontaneous abortion are mostly about 1 week. The bleeding symptoms are usually mild and the amount of bleeding will not exceed the normal amount of menstruation. At this time, we can continue to observe and, if necessary, use anti-inflammatory drugs to promote uterine contraction and blood circulation to promote the discharge of accumulated blood. However, it should be noted that if the gestational period is large at the time of miscarriage and the bleeding is heavy or even dripping for more than 2 weeks after the expulsion of the gestational sac, it is necessary to go to the hospital for ultrasound examination in time, as it may be an incomplete miscarriage with residual villi and trophoblast in the uterine cavity. Women with this condition need to be treated as soon as possible with pro-uterine contraction drugs, blood-stasis-boosting drugs and broad-spectrum antibiotics. If there is no significant improvement after 1 week of conservative treatment, the uterus needs to be cleared as soon as possible to help expel the residual tissue from the uterus. In cases of particularly heavy bleeding, blood transfusion may also be required to resuscitate the patient.
