TL; DR: I have cramps after sex.
Historically, I've had pain after sex. However, it seems to be getting worse.
It feels like period cramps, and it happens most often in the days between when I ovulate and when I have my period. It used to be just immediately before my period but now it's the whole stretch of time. It also used to be only with heavy cervical stimulation, but now it's with pretty much all penetration. It doesn't seem to matter if I do the penetrating with shallow or g-spot toys, or if my partner does it with his maybe a bit bigger than average but not humungous penis. It doesn't hurt during sex, but in the hours and now DAYS following it.
I have a Mirena, about 20 months in. My periods are very regular, although I also experience a tiny bit of spotting and some breast tenderness at ovulation. I get tested for STDs once a year -- all negative as of June 2012. I've had unprotected sex with one partner since since that, but he has not had unprotected sex with anyone else in several years. All of this is to say that I don't think I have an STD, and I also have no other symptoms like discharge, lumps/bumps, etc.
Any ideas about WTF is going on? How to prevent it?
My one suspicion is that while I've never had laproscopy, I have a number of the symptoms of endo. I kind of wonder if this is endo-related, and while the Mirena is suppressing the other symptoms it's not taking care of this one. Anway, thoughts welcome.
