If you’ve ever experienced pain after an orgasm, plz continue.

So, I couldn’t find a group to post this in, but I have a question. Has anyone ever experienced pain on side after having an orgasm? I’ve never experienced this before, but the last few times I’ve had some moderate pain on the left side after having an orgasm. It doesn’t last but maybe 5 minutes, but it’s freaking me out. I’m not ovulating. I’m about a week away from starting my period. Intercourse doesn’t hurt at all, there’s just the pain afterwards. (& yes it’s only after having an orgasm.
