I had sex with my girlfriend. The condom size I chose was a little small and it did not cover the entire penis. It was not covering the penis at 30 percent near the base. Also it slipped off at one point and I was unknowingly inside her for sometime. I think I did not ejaculate in her but I can't be 100 percent sure. She ate an ipill 8 hours after this and 2 days before she was to ovulate. Can she get pregnant?
