Etonogestrel
"So I had implanon for 3 years and loved it. I got it because my cramps would so bad I would have to leave school, and my periods were really heavy. For the first year, I had really irregular heavy periods, but after that my periods stopped all together and now I don't have one at all. After the implanon my doctor told me about nexplanon which is basically the same thing but it's not. I've had nexplanon for 1 year and have had no sex drive, terrible anxiety attacks, and have gained about 15 pounds. Getting it taken out ASAP"
