Hi ladies, I am one of those affected by the Mirena I suppos. I had it put in Nov of 2005 ever since I have had spotting, pains, acne and the worst part weight gain yes, I have gain an incredible 39 pounds but in the last few month i have only been able to lose about 19 but still that keeps me with 20 extra pounds. When i got prgnant I only gain 18 pounds.
