Etonogestrel
"I've had Implanon for almost 2 months now. After the first 2 weeks I got my period and to this day I'm still bleeding. Some days it's very very light, some days it's heavy but most days it's just there. It's only enough bleeding for a light tampon, but the point is I'm still bleeding. This is my biggest complaint about Implanon and I'm hoping it'll stop eventually. But the only other side effect I've gotten from this is the occasional KILLER headache, but an 800mg Motrin takes that away. In fact I think I feel one coming on right now. I can't complain too much, every other birth control I've been on has failed me hence my 2 kids."
