Depo-Provera
birth control
"I was on the shot for 2 years. I'm 5'3 120 pounds naturally. I weighed up to 130 while on the shot. It is extremely effective for protection against pregnancy. Although I have no sex drive and terrible mood swings and weight gain in abdomen, face and buttocks. The pros would be clear skin and effectiveness against pregnancy but wouldn't recommend it for short term birth control or for women who gain weight easily. Took my body almost a year to regulate itself after stopping."
