no period after provera

After 51 days of no period, my doctor prescribed provera for 10 days.  It has now been 5 days since my last pill, and I still have not gotten my period.  We have an appointment on Tuesday to discuss next steps considering how irregular my periods are (sometimes 33 days, sometimes way longer), but I was wondering if anyone else has taken Provera and then not gotten their period.  What might this mean?

Usually if you do not bleed after Provera it means that you either have low estrogen or you have some kind of uterine blockage. I took Provera twice, and had no bleeding afterwards, so now I am on a course of estrogen and Provera.
