Mirena Mirena Coil, Placebo Group, Doctor Don, Horror Stories, Medical Advice

I don't honestly know what to do. I've had Mirena since three months after the birth of my first child and for the first 18 months, everything was GREAT! I mean, no periods, I worked out a lot and lost all my baby weight in a few months, no cramping, etc. However, for the last three months, I've been constantly bloated, gaining massive amounts of weight, even though I diet constantly and religiously and have been intermittently spotting. I've also had some mild cramps, nothing terrible, but more than I have had since my pregnancy. I will say that my physical activity dropped off about a year ago, as I was training for a 500 mile bike ride, but the weight gain didn't start until about three months ago. I've always, always been a thin person and healthy eater, and I am just wondering if the Mirena has now started to do something to my body that it didn't do before, or maybe I just need to start going back to the gym 6 times a week.
