Hello dear Understand your concern According to your history your pregnancy is advanced (4 months that is 9 week). You should consult the gynecologist for abortion of pregnancy. Pelvic examination, USG, Hb should be done before the abortion that confirm the intrauterine pregnancy. Following are the method for termination of pregnancy that between 12-20 weeks: Surgical treatment: suction evacuation Medical treatment: 1. Intramnionic injections - prostaglandins, hypertonic saline, ethracridine lactate. 2. Vaginal route: misoprostol 200-400 ug every 3 hourly. Induction abortion time will be around 14-15 hours 3. extramnionic injections- ethracridine lactate & prostaglandins So better option is surgery as you had no any signs of abortion after taking medicine without the guidance of gynecologist. Side effects of drug will be like excessive bleeding, incomplete abortion, abnormal development of pregnancy, infections, heaadache, back pain. These side effects are bearable. But in surgical process chance of side effects are very less and success rate is high in advanced pregnancy if it is dune by experienced gynecologist under aseptic condition. So better to go for surgical process Hope this may help you Best regards Dr. Sagar
