Etonogestrel
"I've been on nexplanon for 2yrs and 9 months(03/2013). It has been the worst mistake ever. I've had sore breasts, bad acne, extremely weight gain, severe headaches, no sex drive, blurred vision, and constantly hungry.  I just had it removed 12/9/15. I couldn't take any more. When I got it removed I felt something lift up off of me. I feel like a new person. The breast soreness went away instantly. The only thing I see good with it is no periods and I didn't get pregnant. I didn't have that many symptoms with the implanon which I had for 3 yrs before getting this one. But to each his own. This is my experience but everybody different."
