birth control
"After 2 years on Depo-Provera I decided to stop because I was concerned about not having my periods.  My period didn't come back to normal until after 7 months, during this time off Depo I realized that suddenly my mood had improved and I wasn't sad all the time anymore. I switched to Alesse and now realize how bad Depo was for me. It made me moody all the time."
