IM DEFIANTLY NOT PREGNANT

For that I’m certain I’ve been celibate for months and gotten my period

I took out my iud sometime around December of last year.

My periods have been normal since then but lately even before I get my period I have pain in my ovarys.

When I was younger I used to have pain in my pelvis while I was on my period

I’ve been getting back pain with it as well

Does anyone have any experience having a hormonal problem for a long time after removing an hormonal iud

Or could this be a cyst or something else like cancer.

Please help
