I had to take Plan B in November because of a sexual assault. I have had pain in my lower pelvic region since I took the pill. The pain is typically on both sides, but it is occassionaly one-sided. I spend about 2-3 weeks a month in pain. However, my cycle has been normal the whole time. Prior to this, I never had any PMS symtoms nor did I really have cramps. I may have very mild ones on the first day of my period (not typically), but they were nothing compared to the pain I am having now. Last month about the time that I was ovulating, I got extremely nauseated and I was in horrible pain. Since I have never really had cramping before, I think that it is very unusual for it to start since I am 24 now. If the pain was still due to Plan B, I would think that the hormone would have messed my cycle up. Has anybody had problems like this from taking Plan B?
