Etonogestrel
"I've had nexplanon since August 2014. I had a period for a few months, which was annoying! Then I started to have normal to heavy periods and I never knew when they would come. But, I knew when I was about to start a period. I started breaking out EVERYWHERE! I would get headaches, increased appetite, which made me gain weight, I would have mood swings and not feel like myself, and I would even get tender breast and nausea. When I'm bleeding, it last for up to 10 days and it's super heavy. I never know when it'll end and I never know when it'll start. I even spot between periods. This birth control SUCKS! And I would never recommend it to anyone. The only good thing about it is not getting pregnant. I cannot wait to get it removed!"
