Etonogestrel
birth control
"Implanted June 2013. Experienced no pain inserting. My arm was numb for a few days from Lidoderm. I spotted for about a month and a half, which I expected. It's been 8 months now, and I seriously only bleed once every few months. I'm surprised to see so many reviews of non stop bleeding. I've had nothing like that. 
My only side effects I notice are acne and night sweats. No mood swings or emotional thoughts.
Love this birth control!"
