I took Plan B two weeks before my period was due and two days after having unprotected sex. I had unprotected sex five days after taking Plan B . I had a "period" about four days after that (which was a week earlier than my normal period). My cycle is always about 26 days apart. It has been 34 days since the period I had after taking Plan B but if I were to follow my regular cycle I wouldn't be due until next week. If it possible I am pregnant or is my period going back to its normal cycle? I doubted that I am pregnant because I had my "period" after having unprotected sex but then I read that Plan B can cause bleeding that isn't a period. Is this accurate?
