Hi, I had sex last week, but I realised that my partner's condom had broken, so almost immediately after sex, about 40 minutes I took Levonelle 1500 (the morning after pill) a day later I had the normal side affects, I had a substantial headache, my stomach hurt and I felt ill, two days later these side affects had dissappeared, however, yesterday, 5 days after taking the pill I realised that I had bled heavily, but it was a black discharge, and I had stomach cramps, this continued today, but on a lesser scale, I have arranged to see my gyn, but I would an opinion anyway as to why this has happened
