Pre-cum and pregnancy

So here is a scenario that I was just wondering about, so let's say that you and your guy are engaging in foreplay and he pre- cums like 2 times and then like 10-15 min later after you are still engaging in foreplay and he puts his penis in you while not having a condom on just for a few thrusts and then takes it out and doesn't cum at all, is it still possible to get pregnant and what are the chances?
