Copper iud

I want to switch from the shot to the copper iud i can’t deal with these extra hormones anymore😭 but the first thing is do i need to wait to get my period once i’m off the shot to get the iud? and i’m also very small (4’11 and 85 pounds) so i’m not sure if that will have to do with my uterus being big enough, and have any of you liked the copper iud/disliked it and what was the reasoning? the thing i’m worried most about is 1 it coming out of place and 2 coming off of hormonal birth control since my sisters have experienced bad depression after coming off, i really just want to get on a birth control without hormones i’ve tried the pill but i’m bad at swallowing pills and as you know i’m on the shot now i just want to not have to worry about it! please leave your thoughts thank you!💕
