Etonogestrel
"I have had the implanon implant for the past 7 years. My experience has been very positive, I have had complete loss of period since getting the implant and no noticeable side effects apart from a lower sex drive which I have only discovered since getting it removed. 2 months ago I had my third implant removed after talking with my boyfriend and deciding that I no longer required birth control and would like to experience my natural body cycles again. I have had a few side effects since getting it removed but nothing too bad (some break outs, exhaustion, lack of motivation), only my period still hasn't returned yet. My doctor said it may take a few months, so hopefully it returns soon."
