It's amazing that I have spent most of my life trying NOT to get pregnant. I thought since my mom was one of thirteen kids and I'm one of five that my genetic chances of conceiving were pretty good. Last year I decided to go off of birth control and my period stopped coming as well. I am in the military and I deployed to Iraq in September of last year. Before the deployment I took birth control again because I was getting anthrax shots and was scared of getting pregnant and injuring my unborn child. I got my period just like any regular girl would.
