Pros and Cons of IUDs??

Rachel
Please tell me your personal experiences with the IUD and which kind you used!
I used to be on the pill for 6 years, but over time I had absolutely no sex drive and my boobs were hurting through the whole month nonstop. I don't really want to be on anything with hormones again, but I heard that the hormonal IUD has a different kind of hormone and with a lower dose. The copper IUD doesn't have hormones, but I've heard it can cause heavier more painful periods. Not sure which route to go.
