Can you get pregnant this way?

Vday my boyfriend and I had a lot of sex and used condoms. We are not trying to have any kids and I just got off of birth control so my fertility levels are pretty high and I am ovulating. Well, he took the condom off and not even a few minutes later, out of nowhere, enters me. I didn't stop him cause i thought "he already came" but my friend says that you can still get pregnant that way. What do y'all think!? I'm not sure what to think...
