Different options are available for termination of pregnancy at different gestational weeks. Pregnancy can be terminated by abortion in the third trimester and by induction of labor in the middle trimester, that is, between the third and seventh months of pregnancy. After the seventh month of pregnancy, clinical medicine does not recommend termination of pregnancy by aborting the child. The best choice for women who are ready to abort is to do so in the second month of pregnancy, when it is easy to operate, less harmful to women, and quick recovery and not easy to leave sequelae. 1. medication abortion: within 49 days after menopause, the pregnancy sac can be seen in the uterine cavity under the B ultrasound, at this time, you can choose to perform a medication abortion. However, it should be noted that patients with drug allergies should avoid using this method of abortion. In addition, there is a risk of incomplete removal of medication abortion, if there is residue, the residue is small and can be discharged by medication again, if the residue is more than 1cm, further treatment of uterus removal is needed; 2. Surgical abortion: usually within the third month of pregnancy, abortion can be performed in the outpatient clinic and painless anesthesia is feasible. If the pregnancy is more than three months old, the pregnancy usually needs to be terminated by means of medical abortion with the operation of uterine evacuation; 3. Induced abortion: according to the week of pregnancy when the abortion is induced, there are mid-term induced abortion (before 28 weeks) and late-term induced abortion (≥28 weeks), which is a way to terminate the pregnancy by artificially inducing contractions of the uterus. Since induction of labor is followed by a clean-out procedure, which is more harmful to a woman’s body, it is important to try to terminate the pregnancy at an early stage to avoid the development of induction of labor. Miscarriage and induction of labor are more harmful to a woman’s body, so careful consideration should be given before miscarriage and induction of labor. After the operation, you need to pay attention to rest, choose light and easy to digest food, pay attention to keep warm and avoid cold stimulation. At least 2 weeks after the operation, sexual intercourse should be prohibited and bathing should be avoided to reduce infection.
