Etonogestrel
"I love love my Implanon. I have had it for 2 1/2 years now and it puts me at ease.  I never have to worry about forgetting a pill or taking pills late, also, it's not affected by antibiotics! I have very light periods every couple of months for a day or two that are easily managed with panty liners. I have noticed a decrease in sex drive, however not having a little one right now is definitely more important to me.  I will be getting it removed soon and will without a doubt get a new one."
