How crazy is this?? We share the same name, age, # of children, time on Mirena AND symptoms! Twighlight zone...doo doo doo doo...LOL! I'm having surgery on Friday to get mine out....I have all the same symptoms + muscle aches/joint aches,headaches...I too, gained exactly 10 lbs. in a month and a half. Mirena makes your body think you're preggo-hence all the symptoms. I hate it-haven't had a period since i got it-only good thing besides not getting pregg...NOT worth the agony, especially with 4 kids to care for. Good luck mamma...let us know how you are doing!
