3 months is induced labor. What does abortion mean? Miscarriage refers to the termination of pregnancy within 70 days and it includes both medication and abortion. Medical abortion is the termination of pregnancy within 49 days of menopause by medication. Induced abortion is the termination of intrauterine pregnancy within 70 days of menopause by negative pressure suction. The fetus is not fully formed in this period, so this is the method of abortion. Induced abortion refers to the process of helping the fetus to be delivered by drugs or other means when the embryo is already formed, and this period depends on the size of the gestational week and then different operations are carried out. So 3rd trimester pregnancy is induced labor.
