I'm a 20year old woman who was diagnosed with stage four endometriosis . I was taking 200mg of progesterone , than when that didn't work I started taking 15mg of norethindrone and that still didn't work for pain or anything. So my doctor gave me two options, get pregnant or take lupron. And as far as what I have Heard and read about this medication... I do NOT want to take it. The weight gain, acne, mood swings, hot flashes, everything. I'm so scared I don't know what to do. The nurse told me I'd have weight LOSS not weight gain, but I feel like she's lying seeing as how everyone says they gained substantial amount of weight... Can anyone tell me about the side effects.. please.
