Levonorgestrel
"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've started notice watery discharge, heavy mood swings, depression (cried about everything and anything), constantly feel like I've swollen a balloon, no one is allowed near my tummy, and picked up about 5kg'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'm scheduled for op today. Just want to feel normal again! Would not recommend!!!"
