Etonogestrel
"I hate it. I've had it for 18 months. It still hurts in my arm. My hormones are out of control. I'm depressed all the time. I have always had intense  pain from my periods but its so much worse now. I bleed for weeks then stop for a couple days.  For instance I've been bleeding for over 3 weeks now. the weight gain is horrible!! 30 pounds that now matter what I do I can't lose!!! I wish I had never gotten this horrible thing."
