Possibly of pregnancy?

I still see my ex (who I’ve loved since we were 14 and were now 23) we hang out, go to the movies, go out to eat, hiking, and of course we end up having sex. There was this one particular we did it a couple weeks ago, with a condom, but the condom was slowly sliding down. It looked as though his cum went up the condom and we were trying to figure out if it found it’s way out.

Till this day we still don’t know. I am now 11 days late. I’ve been feeling mild cramping so I think my period is finally coming! But nothing .. I’ve also been pretty nauseous to the point where I almost throw up.

I feel like this can all be in my head, but I’m too scared to take a test even though he said he wouldn’t freak out if I am pregnant.

Did anyone else have a similar situation?
