I know some people say that you can't experience pregnancy symptoms within a week, but here goes... I have been on the pill for two and a half months, nearly three by this point. I have only missed a pill once, and that was over a month before I had sex that I missed it, and I had gotten a period after the missed pill as well. I have been late on my pill five to six times, but never by more than an hour. A week ago, I had sex with my boyfriend, and he did finish off inside of me. After sex - almost immediately so - I did experience bloating and constipation, but those symptoms are slowly beginning to die down now. However, I am having very mild, not-so-painful cramps at the moment, and it has been exactly a week after sex. The kicker is, however, that I am due to have my period within the next few days. (Probably 5 days tops. My periods tend to be a bit irregular by a few days in either direction.) Considering my history of taking the pill, and my cramps, is it likely that these symptoms are just PMS symptoms, and not pregnancy symptoms?
