Copper IUD and acne

I have had the Paraguard IUD for 7 months, it is effective but there are still many side effects that I feel may not be explained upfront. I experience cramps so much worse, a few days of the month the pain magnitude is so bad it affects my normal functioning and focus. I have experienced late appendicitis pain and these cramps are consistently quite a bit worse. I also developed pre-menstrual cramps a week before menstruation, which are also quite bad. Aside from this, I developed some acne around my chin and jaw that I did not have issues with before. The cramps have not gotten any better in the 7 months I have had it since insertion.

Good

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.
