Doc i had unprotected sex after my regular period ended and then i had the morning after pill and now after 5 days i am bleeding whyam i pregnant?

Maybe not, but...: Taking Plan B can alter the timing of the current menstrual cycle and the upcoming cycle. Bleeding or spotting should be back to usual, after 3-6 weeks or so. One should check a urine pregnancy 3 weeks after taking Plan B, to make sure there is no pregnancy. Home urine pregnancy tests are very accurate, and sold everywhere.
