Etonogestrel
"I've only been on Nexplanon for a couple of months. I switched over from the Depo shot, which made me gain excessive weight after having my son (whom I got pregnant with while on the pill). My reasons for switching were weight gain, mood swings, and loss of sex drive. Since I've switched, I have 180'd. I've lost 3 pounds in only 3 weeks, and my other issues also seem to be resolved and I have had no issues with spotting thus far. I could not be happier with what I've gotten, my one and only issue is that my arm seems to itch where it is. I can deal with that as long as I'm not dieting and gaining anymore. I know that this form of birth control affects every individual differently, but I do want to say, it works great for me!"
