Etonogestrel
"I've had the Nexplanon for about 2 months now. The first month I had about three headaches a day, now I get about two a week. I've bleed for a month straight, got a break for a couple weeks but it's back again. I do get nauseous here & there, & my skin is a lot more oily but other than that I can't really complain. I do recommend  it became I know no birth control is perfect."
