I had sex with my boyfriend and the condom broke, I took the morning after pill about 27 hours after we had sex and I had pains for a whole week and I felt sick and then I got my period exactly 1 week after taking the pill. But it wasn't a very heavy period, it was much lighter than usual. My "period" is almost over I have had it for about 4 days now, is there still a possibillity that I may be pregnant and that the pill hasn't worked because I waited too long? I was told to wait 3 weeks after taking the pill before I took a test, should I still take one?
