Etonogestrel
"I would never recommend implanon (the rod) as a form of contraception to anybody, I have had mine in almost for the full 3 year term as I was on the pill and kept forgetting to take it, as I was only 18 at the time I needed some form of contraception so I came across implanon. It all sounded well and good but the whole time its given me nothing but grief. I have put on 10kgs, sometimes I don't have my period for 2 months then other times it will be every week on and off heavy bleeding, I am so lethargic and never feel like going anywhere or doing anything and I've also been diagnosed with anxiety since being on this.  The headaches are constant! I CAN NOT WAIT TO GET IT OUT! WOULDNT RECCOMEND TO ANYBODY! especially young girls!"
