Taking clomid with PCOS..

Y’all I need help..🤦🏼‍♀️🤦🏼‍♀️ so I started taking clomid on August 30- September 3. He started me on it before my period ever came.. I don’t have regular cycles AT ALL!! I went back to the dr Sept. 9th, and he said I would ovulate in a couple days.. Cut to the chase. How long after taking the clomid should my period start or I test positive??
