Took plans B on the 21, was ovulating. Took it with in 6 hours of intercourse. Had cramps on my side, which after a few,days moved to my upper stomach. Now 12 days later I still have cramps but now on lower stomach, period like cramps. Spotted a very bit, could barely see it when I wiped. Period scheduled to start on 5th. Concern is not only pregnancy, but eptopic one since my cramps seem to have lasted longer then most I've read.
