I'm 35 and had Mirena inserted on April 7, 2009. I didn't notice any side effects, until now. I've always been on the petite side 4'11" & have weighed between 94 - 98 lbs. I could eat everything & anything, never exercise and not worry about gaining weight ever. Now I weigh 106, which doesn't seem like a lot to most people, but it is for me. The weight I've gained is in my stomach area. My pants now fit snugly around the waist & I've thus developed an ugly "muffin top". So I can't wear form-fitting shirts because I feel like everyone can see my "muffin top". I've never felt so unattractive before. Most people get mad & say I look the same. But I know my own body & know this is unnatural. I pretty much don't have a sex drive either. I'm never "in the mood" and just go through the motions numbly. I've also become a mega-bitch. I feel like I'm angry at the world & always trying to pick a fight with my boyfriend. I hate being this way & am thinking of having Mirena removed very soon! The only positive thing about Mirena is you don't have to worry about anything: no daily pill or messing with condoms. Also, my periods are super light. Of course, I know everybody's body is different and will react to Mirena in certain ways. Just thought I'd post to see if anyone has had similar side effects.
