Copper IUD and negative mood

I’ve had it for over a year, I’m happy with it since it’s been effective in preventing pregnancy but I’ve all the sudden been getting weird side effects and hormone imbalances and bloating.

I wanted the copper IUD because it was non-hormonal and my DR said the only real side effect was worse periods (which she said would be fine for me because my periods are were not too bad in the first place. Insertion was not as painful as I thought it would be. Periods have become extremely painful and mood has definitely suffered

This was super painful to implant and more pain each month I used it during my period-longer and heavier as well as cramping and spotting each month at ovulation. Eventually I had the device removed and I started taking a birth control pill to regulate my hormones in hopes of lowering instance of migraines due to hormonal fluctuations. Now on a pill designed to prevent hormonal migraines, I realize that during my IUD years I had much less frequent migraines so perhaps there is no correlation between my migraines and birth control.
