Hitting my cervix?!

This may seem like a dumb question, but I figured you ladies would know best because to be honest, I’m clueless on this.

I’ve been with my SO for years. We had sex while I was ovulating this cycle (I am on Birth Control)

Fast forward

Yesterday during intercourse it felt as if he was hitting my cervix. Which has never happened before. I read it could be due to lack of arousal, even though I felt quite aroused. So I brushed it of. Then it happened again tonight.

Could this be a sign of pregnancy, my cervix lowering? Or am I crazy lol

Thank you for your help! I’m quite uneducated in this area ♥️

EDIT: I should add I’ve had sex all throughout my cycle and have never had an issue before. This is the first time I’ve experienced this, not sure if that helps!
