Vaginal bleeding in the second month of pregnancy is usually not abortive if treatment is actively arranged. If the vaginal bleeding is due to congenital genetic defects of the embryo, the success rate of amputation treatment in this case is relatively low. The specific method of amputation is bed rest and daily intramuscular injection of chorionic gonadotropin, 2,000 units once a day, until the vaginal bleeding stops, and during the period of time, the blood HCG and progesterone can be monitored. Ultrasound examination should be done to know whether the embryo is alive or not, if the embryo is alive, continue the treatment to stabilize the fetus, and there will be no miscarriage; if the embryo has stopped developing, termination of pregnancy is recommended.
