How likely is pregnancy?

It’s about 3 or 4 days til I ovulate and yesterday me and my SO had sex, (want a baby) but when it was time for him to finish in me his penis kept slipping out bc he was going so hard and it was very wet (sorry tmi) So he only got a little in me but a lot of it was on my vulva. Some also came out when I went to the bathroom to pee and clean up. Is it still a good chance of pregnancy happening?
