Please help: Abdominal pressure after sex?

Hi, my boyfriend and I had safe sex. We tried a new position, and I could feel his penis pushing in differently/ uncomfortably. We switched positions and everything was fine. That was a few minutes ago.

Now, I’m feeling an odd and uncomfortable pressure on the right side of my lower abdomen. It feels like there’s pressure on my bladder as well.

I have no UTI because I just had a urinalysis taken two days ago and the doctor said lab results were all normal and healthy.

Anyone else experience a weird pressure that’s not necessarily painful after sex? Please help! Super uncomfortable. Could he have displaced something? 😂
