"i&#039;ve been on the depo shot for 1 and a half years. i love it because i&#039;m not getting any periods and it&#039;s not like the pill having to remember it daily. however in the course of being on this shot i have gained 70 pounds. i&#039;m always hungry and i get very moody. i also have extremely bad headaches. i&#039;m switching to the nuvaring because my weight gain is unbearable and my headaches are chronic."
