Abortion is the artificial termination of pregnancy, and the specific methods include medication abortion, induced abortion and induced abortion. The method of abortion needs to be decided according to the duration of pregnancy and the specific requirements of the patient. Abortion can be performed medically up to 49 days of pregnancy; abortion can be induced up to 80 days of pregnancy; if the pregnancy is more than 80 days, abortion must be induced and hospitalized. Usually the best time for abortion is around 45-50 days of pregnancy, the greater the gestational week the greater the risk. Before abortion, women need to prepare for vaginal cleansing, improve relevant laboratory tests and exclude contraindications to abortion to prevent more serious complications. If the pregnancy is more than 40 days old, you can go to the hospital for an ultrasound and HCG test, and according to the size of the gestational sac and other relevant indicators, you can choose the time of abortion and the abortion method according to the medical advice. Therefore, if a woman does not want to have children, it is recommended to use good contraception; in addition, it should be noted that it is recommended to get pregnant after six months after the abortion.
