A.K.A ⚡️💪🏽 • Keto+HIIT= happy me🥓🍳🥗

So I'm 16 years old and I am very interested in IUD's

I'm most interested in the copper IUD, but i already have crippling cramps and i rather my period go away which wont happen with the copper IUD.. Its at the top of my list because its non hormonal.

I don't know the difference between the other three hormonal IUDs. I was hoping that you guys can help me out with which hormonal IUD lasts the longest and has many benefits with the least negative side affects.

Also, please tell me your experience with you IUD please😊.
