Mirena Side Effects?

So i have been using the Mirena IUD for 2 years so far and want to discuss the side effects with my doctor soon. it's not been too bad, especially when I consider how much trouble I hear everyone else having with all the ither bc methods. However, it is hormonal so I have struggled a bit with weight gain, acne, mood swings, occasional headaches, and of course, no period. Has anyone else experienced these things?
