Condom fell off

Okay: Yes, I know anytime you have sex there is a chance of pregnancy. I also already know that I can take a test to be sure. That’s not what this post/question will be about.

So I know that it’s possible for pre cum to get you pregnant but it’s just pretty rare. What happened to me was the condom came off inside of me but when I took it out there was still a lot of semen in it. So do you think that it’s rare to get pregnant that way or is it basically like having point blank unprotected sex?

The facts are:

1.) I’m not on birth control. 2.) It was Day 2 of my green ovulation days. 3.) He came inside of me but with a condom on. I’m assuming the condom was on that entire time and just fell off as he was pulling out when he was finished because there was semen still in the condom when I took it out.
