Provera & Clomid

Julia
I have PCOS and am not able to generate a period or ovulate on my own. 
I started taking Provera today to induce my period. My doctor said to take it for a week but If bleeding starts at 5 days into the course, stop taking the provera, count that day as cycle day 1 and start taking clomid that same day. 
​I know that people usually start taking clomid at cycle days 3-5. Has anyone started taking clomid on cycle day 1 or does anyone know why the doctor has started me on Clomid on it then? 
​Would love to hear everyone's provera & clomid experiences. Fingers crossed this will help!
