"i&#039;ve got the implant in august of 2014 right before i left for college, and not its gonna be june 2015 very shortly. so i&#039;ve had the implant for about a year, and it&#039;s very effective. i was worried about gaining weight as well, and on this birth control, i didn&#039;t. i actually lost weight. i always forget that i even have it because it&#039;s not a nuisance like the pill or the patch is. you get it inserted and you&#039;re good for 3 years! love it."
