Copper IUD horror stories

Hannah • Fur mamma. Heathen.
I've always heard this is a dangerous form of birth control. And I've seen a lot of horror stories on YouTube about it. 
I really need birth control but I can't bring myself to put hormones into my body, so I feel that the copper IUD would be the best option. 
Has anyone tried this form of bc before? How did it work out?
