My boyfriend and I have been in a serious relationship for a while now, we have sex often but not too much. I'm on birth control and the last time we had sex, he pulled out to get a condom and he saw he was cumming and didn't realize. We aren't certain he came in me, but I'm FREAKING. What are the chances of getting pregnant on birth control if he might have came in me? Note, I have never missed a pill, I'm not on medication and always take it exactly on time or at most an hour before. Please help
