Cramps after sex

Ni

Alright so last month I was WONKY on my BC Pills (I’d miss a day then double up, miss a few days and still double up) but I was taking them. My boyfriend and I had sex a few times, all unprotected and he never pulled out. This was at the very beginning of October. But the past two weeks I have been very strict on my bc but on accident I left it at school this weekend so I’ve been without it for three nights now. Nbd because my bf and I used a condom today.

During sex today, however, we moved to a position we’ve never tried before and it made my uterus hurt BAD. A minute later we moved to missionary and it didn’t hurt as much. But when we were done, I was just curled up in a little ball in so much pain. My lower stomach, like my uterus, was hurting like a BITCH and it was like that for a good 10 minutes before I could move some more. It still hurts now and it’s been 3 hours, it just doesn’t hurt as much.

The problem is, my period cycles these past 4 months have been extra long, 34-41 days, and right now I’m on the 39th day and I still haven’t started. Im afraid the cramping is a sign of pregnancy? Im going to take a test tomorrow evening
