Etonogestrel
"For the most part my experience has been positive, with a few annoying side effects. First of all, I had been on NuvaRing, which made me absolutely insane. I would cry for hours for no reason at all and became depressed randomly for no reason. I also have NEVER had acne, like maybe five pimples a year since entering high school. The great thing about Nexplanon is it's so easy, insertion was extremely quick and painless. Mood swings have completely disappeared and it's actually improved my mood. I spotted for the first week and now my periods have stopped. I get spotting maybe every three months for a day or two. One major downside: I get acne frequently now. Not enough to make me remove the implant, but its a bummer."
