birth control
"After my 2nd pregnancy I used natural birth control method, but about a year later I got my first period and surprise! I got pregnant. After my third child was born I got on the Depo-Provera shot. Other than slight pain on the injection sight for a few days I also noticed both times after getting the shot I get moody and angry easily. (I feel bad for my family) but after a short while I usually go back to normal. I'm guessing its just the change in my hormone levels."
