I had unprotected sec on December 2 but I wasn't ovulating. We kept on worrying so to be on the safe side I took postinor 2 near the 72 hour mark on December 5. We got bit frisky again and ended up having sex a few hours after I took the first pill. All seemed well until last week Friday (December 12) I started to bleed. I thought it was my period as the leaflet said it may cause irregular period but now its December 19 and I am still bleeding although its not light and I'm having minimal abdominal pain and worrying a lot. Should I just relax and wait for the bleeding to stop or see a doctor immediately?
