Last night was my boyfriends and my 1 year, and we had sex that night. I have been taking Birth Control for 2 years but have been off and on. and the past 3 months, i have been off the pill completely. I recently have been back on the pill, but only for 4 days and in those 4 days i have not been late taking them at all. Well while having sex with my boyfriend, as he was about to bust and pull out, I had an orgasm and he ended up not pulling out... whats the chances of me being pregnant? should I take a plan B pill? or not even stress about it?
