Depo Provera

I have discontinued my Depo Shots for a year, this month. I never had a period when receiving the shots, and even a year later, I still have not had one single one. I'm becoming very worried because my boyfriend and I want to try for a baby and be successful in that before he leaves for basic for the Air Force in a month and a half. Is there ANYTHING I can do to get my periods and my cycle back?!
