Chances of pregnancy?

So normally when I have sex with my partner we normally start off without a condom and before he comes, he puts one on. Or he pulls out. Either or.

There have been a few close calls where he almost came in me or a little to close to vag but we always checked to see that he didn’t.

We did anal a few weeks ago for the first time and he came in my butt and I sat on the toilet to make sure all of the cum was out and wiped myself as best as I could.

Long story short, I’m 5 days late on my period. Which isn’t a big deal but I’m kinda wondering why I haven’t gotten it (I’m not usually late on my period). I’ve been having symptoms of my period for the past three weeks and nothing. I don’t want to take a test bc I know deep deep down that I’m not but I would like some opinions or whatever.

I guess I’m wondering if I’m late because I’m thinking about the possibility of being pregnant or something worse?
