The best time to have a medical abortion is 40-50 days of pregnancy, because the ultrasound can indicate early intrauterine pregnancy on 40-50 days of pregnancy, which can exclude ectopic pregnancy and make medical abortion feasible. The 34th day of pregnancy is too early for the ultrasound to detect a gestational sac in the uterine cavity or even if there is a gestational sac, it is atypical and there is no yolk sac, so ectopic pregnancy cannot be ruled out. There are contraindications to oral medication abortion, and patients with glaucoma, hypertension, epilepsy, and asthma are prohibited. The success rate of medical abortion is 80%, and there is a possibility of vaginal hemorrhage, hemorrhagic shock and incomplete medical abortion during the process of medical abortion, so you should be fully informed before using the medication and give good instructions. If vaginal bleeding occurs, go to the hospital at any time and review the ultrasound 7-10 days after the procedure to see if the medication abortion is successful. It is recommended to use contraception for at least 3 months after the procedure, preferably 6 months before considering the next pregnancy.
