I have been taking the pill (prevafim) since early December and have never missed a day. However, since it was Spring Break, I took the pill around different time of the day with no real pattern between the distances apart. I usually take it around 6:30am, nut this week i took it twice around 10:30am and the other 4 around 4pm. My boyfriend and I had unprotected sex, but he didn't fully ejaculate inside of me, he pulled out almost as soon as he started, but there was a delay. It was the third week of my pack where the times were inconsistent, and the weeks before I have been perfect with taking them on time. My period should have begun yesterday (March 15) and it didn't. What are the chances that I could have gotten pregnant even though I never really "missed" a pill?
