Abortion is not possible in the third trimester. Abortion is generally indicated for termination of pregnancy within 12 weeks, when the embryonic tissue is not fully formed and the pregnancy tissue is sucked out of the uterine cavity by means of negative pressure suction. After the third month of pregnancy, the fetus is already developed and formed by a small amount of amniotic fluid and placenta, so the pregnancy can no longer be terminated by negative pressure suction, and abortion can be induced by medication or intrauterine injection of Levanox. For women who do not need to have children, termination of pregnancy should be performed within 60 days of menopause, which is relatively less harmful to the woman’s body. If the pregnancy is terminated at a relatively large month, it will be more harmful to the woman.
