Provera no period

My obgyn started me on Provera on July 30, took my last pill August 3rd. He said I should get my period 4-5 days after the last pill. It’s been 6 almost 7 days and no period. Just cramping and a very little brown mucus type discharge. He said that if I don’t get a period 10 days after my appointment to call him. Called this afternoon and he’s out til Wednesday.

He also told me to start Clomid on day 5 of my period, but no period yet.

Has anyone else had this problem?
