"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&#039;ll see.
