Provera and no period

Emily

I have been taking provera for 3 months to get my periods regular again after a miscarriage and they have been starting about 4 days after the last day I take provera (10 days). But this month the day after I was expecting my period to start I spotted for 2 days. It has now been 14 days since my last pill for this cycle and still no period. How long do I wait to test or should I just go see my OB?
