Ladies Birth control question. I'm currently on the pill thinking of switching possibly to copper IUD. Thoughts? Personal experiences?

25 y/o female ive tried 2 different kinds of pills the ones that fluctuate in hormone levels and the one that stays the same all month (only take 2 sugar pills instead of a week). But I don't like how low my sex drive is or vaginal dryness and my emotions seems to still go crazy so I kinda want to try the copper IUD as it's non hormonal. Concerns are I've heard of people getting pregnant heavy bleeding and bad cramps. Or it can imbed in things it should not and wreck your ability to have kids later. I will be talking to my doctor and getting her opinion but I would like as many opinions as possible. Thanks in advance?
