There is a time frame for abortion and the best time to have an abortion is within 40-55 days of pregnancy and no later than 70 days. Abortion is a common remedy for unwanted pregnancies and a treatment for medical reasons to terminate a pregnancy, and can only be performed when the gestational sac is greater than 1cm in diameter. If the diameter of the gestational sac is less than 1 cm, there is a risk that the abortion process may cause leakage, which means that the gestational sac cannot be sucked out, resulting in failure of the procedure. If it is more than 70 days after menopause, abortion cannot be considered because the fetus has already formed and direct abortion may cause lacerations to the cervix, so hospitalization is required to induce abortion. Patients are advised to go to a local regular hospital for abortion and need routine oral antibiotics to prevent infection after the procedure. In addition, sexual intercourse should not be allowed within 1 month after abortion.
