Hi, I just wanted to add that I have had my mirena for 16 months and it's not been easy. For the first three months I bled continuously and was so run down I couldn't fight off a case of strep throat which caused me to develop Graves Disease (overactive Thyroid) that was12 months ago. I then had a 21 day cycle for 4 months and was utterly exhausted. In the last 3 months have had severe bloating and acne, terrible cramps and nausea. I have only gained 4 pounds but can no longer wear any of my trousers it's so bad. I saw my dermatologist today and she confirmed I now have acne, but said it's unrelated to the mirena - I have to start a 4 month course of antibiotics. It's really getting me down, what are you supposed to live with horrendously heavy periods or the terrible side effects of the mirena?
