I am wondering how big's the risk of being pregnant when I'm on my second month of BC pills, never missed any, was 10 hours late with one pill (first week of second month) and the condom slipped off before my partner withdrew, about a week after the late pill. Most of the leakage was on the bed, yet I took the day-after/emergency pill after 8 hours just to be safe.

I should get my period anytime soon but I am still concerned. Should I be worried?
