"been on mirena for almost 2 years now. 

insertion was painful. felt like very bad cramps and was bleeding for 2 weeks but after that ,my period completely stopped. it was the best thing ever. did not have much side effects.i am a very active person and always concious about my weight. since the beginning of this year i&#039;ve started notice watery discharge, heavy mood swings, depression (cried about everything and anything), constantly feel like i&#039;ve swollen a balloon, no one is allowed near my tummy, and picked up about 5kg&#039;s in one month. went to doctor yesterday and mirena caused very big cyst filled with hormones - no wonder!could not get it out yesterday so i&#039;m scheduled for op today. just want to feel normal again! would not recommend!!!"
