Could I be pregnant?

Lauren

The other day my partner and I were having sex with a condom. He finished slightly before me and as we kept going for another 30 secs or so until I finished, we heard like a sloshing sound. After I finish, we look and see that he got a bit softer in the extra seconds and therefore the cum came all out through the bottom of the condom. It was all around his dick and slightly around the outside of my vagina. We don’t know if any got in or even if it did what the chances are of that little amount actually getting my pregnant. It’s probably a really dumb question and I’ve been trying to brush it off but I’m still anxious about it. What do you think are the chances?
