"i&#039;m 23 years old and have been using depo-provera for a year and a half and i love it. i hope i never go back to the pill. i did gain about 7 pounds the first year but i&#039;m not sure i can blame that completely on the shot. i was able to the extra weight within 6 weeks of diet/exercise. i rarely have a period and even then it&#039;s light and barely noticeable. never heavy bleeding like a normal period and that is awesome. i get my shot in the arm and it never hurts or leaves my arm sore. i also take calcium and vitamin c supplements to prevent bone density loss."
