Help with provera...

Has anyone taken provera (progesterone) and not subsequently got their period?
​I took provera for 1 week as directly and was meant to get my period up to 1 week- max 10 days after the last pill. 
Today is my 10th day and I have no sign of a period. I have polycystic ovaries and have been waiting for my period to start in order to start taking clomid.
​Has anyone been in the same position or know what the next step would be from the doctor. I'm waiting to speak to him on Monday.
