I had unprotected sex, but he pulled out 2 minutes before he busted. A few days later we went with protection, none of which had ripped, and he still pulled out even with protection for safety. My period hasn't come yet, but, I was in the hospital for pains and been using Vicodin and Valium, and phelexeroll(sp) for it. Could these stall my period or make it later?
