Early pregnancy between 35-49 days is suitable for medication abortion, and ectopic pregnancy must be ruled out before performing a medication abortion in early pregnancy. If the pregnancy is less than 35 days old and the gestational sac is not visible on ultrasound, there is a risk of an accidental situation with blind medication. Taking medication for abortion without visible gestational sac formation can also easily lead to failed medication abortion. If the number of days of pregnancy exceeds 49 days, there will be obvious formation of the fetal body and taking medication for abortion will easily lead to abortion failure on one hand and heavy bleeding on the other. Medication abortion is the more commonly used abortion method, which is relatively painless and does not damage the cervix and endometrium, but has the potential risk of causing miscarriage failure.
