Just want to put my mind on ease!

My boyfriend and I had sex on my ovulation day, Cycle 14. I’m not taking any birth control and we did not use condom. We started fooling around and had pre cum before he entered me and pull out when he was close to cum. And We both didn’t cum. But my mind is going around in circle thinking. I feel like I’m being paranoid. But is it possible I could be pregnant? I hope I don’t sound stupid.
