birth control
"I'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'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'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."
