In the case of spontaneous abortion in the early stage of pregnancy, it can usually be completely cleaned up in 7-10 days, the gestational sac development is relatively small in this time period, the placenta has not been formed, and it is easy to be cleaned up. In some cases, the uterus does not contract well, and there may be vaginal bleeding, and the uterine residue cannot be discharged in time. If the vaginal bleeding is heavy or prolonged, you should go to the hospital to find out the specific situation, and if the ultrasound shows that the uterine residue is relatively large in size, you should consider the operation of removing the uterus. After spontaneous abortion, we should pay attention to avoid coitus for 1 month, coitus too early may be infected in the uterine cavity, thus affecting the next pregnancy, after spontaneous abortion, we need to contraception for 3 months, so that the uterine lining can be fully recovered, before considering conception.
