The main reason why doctors do not recommend medication abortion is that some of them will not be clean, and because they will not be clean, they will need to do the operation to clear the uterus, which will increase the chance of infection, and the operation to clear the uterus will also bring the patient two times of pain, so medication abortion is not recommended. In addition, even if the abortion is completely clean, the vaginal bleeding time will be prolonged because of the slow apoptosis of the trophoblast, and the prolonged vaginal bleeding time will increase the chance of retrograde infection. It is recommended to choose abortion or painless abortion, which can reduce the chance of infection, reduce the chance of incomplete abortion, and have a relatively good effect on the physical and mental health of women.
