"i&#039;m 15 and got the shot about 2 months ago. so far, my periods have remained regular. on the downside, i now feel hungry all the time. all i do is eat.. i have these irresistible cravings now. i&#039;m noticing weight gain of course because i&#039;m stuffing my face, but i&#039;m miserable if i don&#039;t eat what i&#039;m craving or when i&#039;m hungry. also, i&#039;ve been having excruciating headaches. i already have migraines. i had them for years, before i got on the shot. but they had stopped when i started a new medicine. now they&#039;re back since i&#039;m on the shot. it&#039;s terrible, hopefully the cravings, appetite, headaches, and also these mood swings i&#039;ve been having get better. if not i&#039;m switching."
