Levonorgestrel
"This device was suggested to me first by my insurance company, because they want to try the cheapest route of treatment first, then by my doctor, who understood full well that the device was not going to stop  the regrowth of fibroids. Decided that we should go forward with the implant, which didn't not help,and  if anything made it worse.  Needless to say  the fibroid is still here, and heavy heavy bleeding lots of pain and being inserted was also very painful. When I went back for my 3 week follow up check up,the mirena was nowhere to be found. After a vaginal sonogram and x-rays they just assumed it was expelled from my body. I  found another doctor immediately and SHE schedule me for a partial hysterectomy within a month's time."
