Etonogestrel
"I have had this birth control since april of 2012; having it changed last year. I have my own bouts of anxiety and depression so that may contribute to some of my issues. But I can say that; I have gained a lot of weight since being on this birth control; even when I was walking 10 miles a day and barely eating I only lost like 15 pounds at most; I started off at 155 with this implant after having my son. Once I started being more active I made it to 140; Now, after just 4 months of not walking 10 miles a day but still being active I am up to 171 lbs. It's ridiculous. I plan on having the copper IUD inserted soon. I also have trouble with breaking out a lot, mood swings, and a non-existent sex drive."
