Etonogestrel
"I got Implanon put in Feb 2013, while I was on my cycle. My cycle stopped when it was supposed to. About two weeks later I bled constant. The Implanon caused me
to have many side effects. I got depressed, anxiety, sad  and hormonal. And I bled constantly until May. Everyone is different and everyone's body responds in a good or bad way. After having it removed I'd say I'm 99 percent better."
