Hi. I'm concerned about my period. On April 8th, I got my period last. I then had sex (with a condom that slipped off) with my boyfriend. We got plan B One Step approximately 10 hours after sex. Then, we had sex again that night, again with a condom. However, we were intoxicated and I'm not completely sure that no sperm got inside of me. I should have gotten my period two days ago. Am I pregnant, or is Plan B just doing it's job?
