Etonogestrel
"When I first got the implant in I had spotted bleeding for like 2 weeks straight, and then nothing. I don't get spotting for months at a time or even cramps, every once in a while I do but at lot less then I used to. Never had anything else but this and I'm so glad because with the pill even 1 day you miss can change everything and now I don't have to worry, love it!"
