"i&#039;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&#039;ve switched, i have 180&#039;d. i&#039;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&#039;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&#039;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!"
