birth control
"I was on it for a little less than a year, and during that time, I didn't have a period for a total of two weeks. I was on my period for almost nine months straight! Not to mention constant acne, mood swings, and I gained almost 20lbs! I didn't get pregnant because I didn't have sex the entire time I was on it; why would anyone feel in the mood when they're bleeding, pimply, fat, and moody all the time?! I know a few girls who got pregnant on the implant, as well, and had to have it removed early due to pregnancy."
