After the first drug abortion, the second drug abortion is still possible, as long as the indications are mastered, for example, between 5-7 weeks of pregnancy, laboratory tests of leukorrhea routine, blood routine, coagulation time and electrocardiogram are all normal, you can choose drug abortion. However, the second medication abortion is relatively less likely to be completely clean than the first one, and the second abortion may result in the possibility of incomplete medication abortion.
