If he didn't cum am I pregnant?

Ok so i know this is very stupid but my boyfriend and I were very horny so he put his dick in me(without a condom) and kinda thrust maybe twice, he didn't cum and didn't before either and I'm 100% sure he did not. I was wondering if it's possible I could still get pregnant? We have used protection in the past and I'm on a birth control. My question is can i still get pregnant if he didn't cum??? I've heard of Pre cum but it was in for like 1min so idk if that can get u pregnant???
