Okay, so I'm not trying for a baby or anything at the moment, but I recently came off my cerelle pill like 3 months ago and after about 1-2 months had a proper period, lasted about 4 days, so I then calculated when my next one would be. I used to have regular periods before I went on this pill which I've been on for like 3 years and haven't had any periods while on it, so I came off to try and get my cycles back to normal for a while. Anyway, I also had unprotected sex with my bf a few nights before my period was due, didn't get EC as I thought my period's due so soon I surely can't be fertile.' However my period was due 6 days ago and still no sign, also have sore nipples, but have had that before and I wasn't pregnant. Have been taking pregnancy tests since my period was due and they've all been negative, but is it too early to tell as I only had sex 9 days ago?? I'm hoping as there's only a small chance of me ovulating at that time, that I'm not pregnant, but I can't be sure. Even still my period still hasn't come, do you think it's just late, as my cycles haven't got back to normal yet? What should I do??
