Hi there,
Let me start off by saying I am NOT trying to conceive. I had sex on 8/12/12 and my last period began on 7/19/12. We used a condom and he didn't cum, but I'm still worried because last time I took Plan B and this time I did not. We had sex for a very long time, probably around 45 minutes but there was nothing wrong with the condom that I could see when he took it off (he would have said something if he noticed anything also). I'm not very regular with my period, but I should get it soon if I'm going to this month. Last night, however, I experienced brown blood that lasted for a few hours and stained my underwear. I had cramps all night but when I woke up in the morning, no period. I'm really terrified that I might be pregnant. But also, my cycle has been a tad funny since I took the Plan B in June. I get worse PMS symptoms than I ever have and weird red spotting between periods. Could this brown spotting mean I'm pregnant or that my cycle is just readjusting or something? Thanks for your input.
