About 4 weeks ago I had what I thought was unprotected sex. The guy swears up and down he wore a condom... but I found NO evidence of one the next morning. Im on birth control, but that was my week I was off, and I had JUST finished my period.

Anyway, I got paranoid, and took plan b within the 72 hr window I could. Last week I wasnt feeling so well, and took my bc pills not at the same time daily and I even missed a dose. I began spotting and I thought it meant I wasn't preggers. I spotted for about 4 days. Then Saturday night I got this horrible pain. It was similar to cramps but about 100 times worse! I expected to start my period Sunday, but nothing came.

With the plan b pill, I know it can cause early or late menstration... should I consider the spotting my period? Im really concerned, a little freaked out that maybe I am pregnant. And that horrid cramping, which lasted for about 20 minutes without letting up. What do you think??
