birth control
"I'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've had the implant for about a year, and it's VERY effective. I was worried about gaining weight as well, and on this birth control, I didn't. I actually lost weight. I always forget that I even have it because it's not a nuisance like the pill or the patch is. You get it inserted and you're good for 3 years! Love it."
