I am 34 years old. I had a early pregnancy of 38 days. Medical abortion was prescribed by my gynaecologist .given unwanted kit of tablets for three days. I got my periods on the first day of having tablet but with spotting and low level of bleeding. Second day aborted portion of the pregnancy came out with little bleeding. Third day no more bleeding. Fourth and fifth day full of heavy bleeding .sixth day reduced and seventh day no thing. To control bleeding and to remove unwanted waste in uterus my doctor suggest me methergin tablet for three days 2 times a day. On seventh day I had a unprotected sex .now i'm afraid that I may get pregnant again. My period cycle is 28 days. I didn't had that methergin tablet for now. Will it stop pregnancy. Else I need to go for I pill? Is it ok to have with methergin.
