Etonogestrel
"I got on this birth control implant in February of 2015, it's been great for me. Like I say, it effects Every body differently, so just because it doesn't work for you, doesn't mean it doesn't work at all. You have to find what works best for you. I've not experienced any weight gain, acne, or anything. However, I've not gotten my period since the day I got it, but not I am bleeding lightly. It's not a full period, but it's not spotting either. Other than that it's been a great experience for me, no problems at all. I reccomdn D to fry it and see if it works for you."
