HELP please getting pregnant after the depo shot

Not really sure which group to post this in....So this Feb it will be two years since I got my last depo shot and I only got the shot twice. Been trying and having unprotected sex for over a year now with no luck. My periods have been back to normal for almost a year now also... Does anyone have any tips or advice for me on how to get pregnant after the depo shot. I have done tons for googling but would like to hear it from you also. Thank you
