The first review is about half a month after the operation, when it is usually recommended to review the ultrasound to see the recovery of the uterine adnexa and to exclude intrauterine residues. The second review is usually after thirty-five days, that is, after menstruation, when the ultrasound is reviewed to see the recovery of the uterine adnexa, and the white belt routine is done to see if there is any infection. If you have a medical emergency after miscarriage, such as heavy bleeding or pain in the lower abdomen with high fever, you should come to the hospital in time and generally do gynecological palpation, routine blood tests and ultrasound to see if there is residue or infection, and if necessary, treat under the guidance of the doctor. In addition, if you do not have a normal period for thirty-five days, you should also do relevant tests, such as ultrasound and blood HCG, to see the degree of HCG decline.
