implanon to IUD. what to do?!

Deja • beYOUtiful
I have the implanon and am hating it for multiple reasons. It was okay at first, but now it's even affecting the type of bras I can wear. I've been researching Mirena and thinking about it, but I don't want to make a switch without looking at all my options. Have any of you ladies switched from implanon to Mirena IUD? Women with Mirena- how does it make you feel? Do you like it? (I know every body is different just trying to get some opinions.)
