No period yet even after Provera

I am 44 and my last normal period was June 20.  Since then, I had one day of spotting on Sept 6 and one day of light bleeding on Sept. 7 but have had nothing since.  I recently went through a 10 day treatment on Provera at a 10mg dosage and have still not begun a period even though my doctor told me that the Provera would jump start my periods.  Up until my last normal period, I was not experiencing any problems.  He had tested my TSH, Prolactin and Testosterone and told me that they were all normal.  Any suggestions on what I should do next?  Are there other tests that I can ask my doctor to run to help figure out my problem or does this maybe mean that I am in menopause or perimenopause?  I am not have any symptoms of menopause that I have read about, though, except for not having a period.
