I took Plan B last month (5/12) because of a scare and my period came a week early. This month I had another scare (I know, stupid) in which I took Plan B again. I should have been around the middle of my cycle when I took it (June 3) and then on June 9 I had period-like bleeding for 3 days (it had tissue and clots in it, plus it was bright red). It would have been 10 days early for my period. Now I am reading that Plan B can cause withdrawal bleeding and that might not have been a period at all. I am freaking out. It has been 12 days since the incident and I took a First Response Early Result HPT and it was negative. I am still really worried though especially when I hear of women who are having their regular periods 6 weeks late after Plan B -- let alone 2 months of it! I started on the minipill in the meantime so that this doesn't happen again, but do you think that I have anything to worry about? Could I still be pregnant?
