I haven't had a menstral cycle in two years. i only took one depo-provera shot, the day i took it was my last period. will my period "come back"?

Depo shot: I would make sure to make an appointment with your practitioner. 2 years of not having a menstrual cycle calls for some testing. The first year after injection may prove from some breakthrough irregular bleeding or no menses at all. Two years is a bit longer than expected to have this. Is that they only hormonal contraception that you have used since then? Make sure to get checked.
