Provera

My doctor prescribed me Provera to start up my period. (It had been 60 days since my last period) I took the Provera for the prescribed 5 days, twice a day. It's now 10 days since I stopped taking it and still no period. Just wondering if anyone had Provera fail and if so what was your next step. This is so frustrating, I just want to get back to normal so we can start trying again.
