Could this lead to pregnancy?

Me and my boyfriend had unprotected sex today and we always use the pull out method. He was about to cum and when he pulled out he accidentally cum on the outter part of my vagina and near my entrance (sorry) I checked and it was quite a bit on my vagina near my entrance. After he wiped off which took him only a few seconds he put it back in with his sperm still on me and I know he pushed some in.. Could that still get me pregnant? Or should I be fine. I'm not worried if I do get pregnant. We would be very excited to have a baby but aren't actually trying but it would be a miracle to have one. But what do you guys think ? Could it have gotten in far enough ?? Sorry if it's too much detail !
