DEPO AND PREGNANCY

I have been on Depo- Provera for 3 years now and I decided to come off of it. I suppose to have gotten my shot In January 2007, but I decided not to get the shot. Now I'm trying to get pregnant and have a baby. I heard that it take a year for depo to be out of your system, but what i would like to know is if there is anything out there that I can take or if there is anything I can do to get pregnant now!!!
