Pain during sex with coil

Hi!

I’ve had the coil fitted for a few years now. About a year ago I had a scan of my ovaries and there was a small cyst- apparently they usually go away.

Anyway recently I’ve been having this pain deep inside- especially during foggy style. I’m really unsure what this could be. I’m a hypochondriac and have researched online and read all about fibroids and the like.

Has anyone else experienced this?
