Pain during deep penetration

Hi, there!

My boyfriend is well-endowed so I have experienced the pain of him hitting my cervix, and the pain when I’m not wet enough. But this new pain is different... and a lot worse. It’s so painful that my whole body gets chills and goes cold for a second. I cry out or gasp every time and I couldn’t stop it if I tried. It feels like it’s pain in my uterus or right ovary?? It’s not pain in my vagina, for sure.

I’ve been having sex for over four years, so it’s not new to me by any means. It’s only when he goes deeper than usual. We’re doing positions that stop him from going as deep as he can, and it’s still happening.

As far as I know, I have no other symptoms; regular periods (on oral birth control and he uses a condom every time) with minimal cramping and an average flow. No pain when peeing, or irregular discharge.

Anyone experience this before? Any ideas what it could be?

I recently started a new job and I’m waiting for my medical insurance to kick in, so I can’t see my OBGYN just yet.

Thanks in advance!!
