Has anyone gotten pregnant while taking provera to jumpstart your period?

I have been on 3 rounds of clomid. I was on the first cycle of round 3rd 150 mg. My periods have been regular unti then. I did several hpt and a blood test confirmed that I was not pregnant. So, my obgyn started me on provera 10mg for 7 days. My last pill was on 12/25 and still no period. I cant start taking clomid until I get my period again.
