A little freaked out

So me and my bf have been together for almost a year and we are both clean of stds so we decided to stop using condoms and i started the pill 2 weeks ago. I take it within 10 mins of 10:00 every night & haven’t missed any. We had sex tonight with no condom and he still pulled out but I’m still a little freaked out tho that i could get pregnant. probably not though right?
