Not on BC..I had unprotected sex on May 29, 2012..he pulled out and I immediately (within an hour) went to Walgreens and bought the Plan b pill. My usual period is around the 10th of the month and I am very regular. I started bleeding about 5 days after I took the plan b pill and it lasted about 10 days. It is now July 16 and I haven't had my period yet and I am freaking out!! Should I be worried about getting pregnant?? Is it normal to be late?? Will my period come soon? Please Help!!
