Hello all!

My boyfriend and I recently had sex without a condom for the first time. In retrospect, I probably was not ready for sex without a condom, but I obviously can’t go back now. I’m on the combination pill, which I have been taking pretty consistently (every day, within 3 hours of the same time, only an hour or so later on a few days) for about 3 weeks. I started within five days of my period. He pulled out and says he is 99% percent sure he did it on time. I’m still concerned about the risk of pregnancy. I’m not looking for medical advice, but if anyone is willing to share from experience, should I be in the clear?
