Mirena
"I am 31. I have had Mirena for 3 1/2 years. I loved it. No periods, little cramping, no weight gain.  I run 3 miles a day 5-6 days a week and watch my diet.  About 6 months ago I got really sick with what I thought was ear infection...nope turns out I am suddenly retaining fluid in the bones in my ears. Pretty painful and I have to take a Diuretic to combat it. Although it is manageable with low salt diet and pills, it gets worse around my period, which has now started spotting randomly...about every 2 weeks. Sometimes I get a sharp pain, cramping and nausea. My back aches for no reason. I am suddenly gaining weight and my eyes are dry, I am always tired. I see the Doctor next week. I think its time to come out, we'll see. "
