birth control
"I got Implanon in July of 2009. A week later, I started my period which was far heavier than I normally get. I bled for the next month, but after that? Nothing! That is a blessing seeing as I have endometriosis and my periods were /extremely/ painful. I have a bit more acne than before and I think I've gained a little weight, but all-in-all... I'm thankful. I'm pretty happy with it."
