Yes, those side effects can definitely be from mirena. I couldn't have posted those symptoms better. Sounds exactly like me!! All summer long i've been wearing unflattering clothes because of my bloated stomach!! We're not even gonna go into the anxiety it caused me. I had it in for a year and a half. Didn't start geting symptoms until about 7 or 8 months ago. I would've never known what I was experiencing was from the mirena had i not found this forum. It's been out for almost two weeks now. The one thing that I've noticed already is my hair isn't all over the house like it was. Not sure if you had that problem, but my hair was falling out in clumps everytime I washed, and I would see it in the vaacum, and kitchen floor. Not balding or anything. Luckily I have long thick hair, or it might be noticeable. Good Luck to you!!
