Half a month after miscarriage, the first thing to look at is whether the miscarriage has been clean, possibly caused by intrauterine residues. In this case, you should go to the hospital to check the gynecological ultrasound to see if there is intrauterine residue. In addition, we should look at the recovery of the uterus and the thickness of the endometrium. If the ultrasound reveals intrauterine residues, the next step of treatment should be decided according to the amount of residues. If the amount of residue is very high, timely curettage should be performed. If the amount of residue is very small, conservative treatment with medication can be given, including oral motherwort granules and intramuscular injection of uterine shrinkage to promote the discharge of residue. If the ultrasound indicates that there is no residue in the uterine cavity, this situation may be caused by irregular menstruation after abortion, there may be endometrial inflammation, look at the thickness of the endometrium, or may be due to bleeding from the trauma caused by surgery, this situation can be temporarily observed as long as the bleeding is not too much.
