accidentally started Clomid on CD1 :(

Aj
So I was given provera 1/13 to jump start my period. The last day I took provera was 01/17. My doctor told me I should expect my period in 2-7 days. Today is 6 days & I just got my period. Well, my doctor told me to start Clomid on my THIRD day of bleeding. I jumped the gun out of pure excitement (for AF coming) & took a dose of Clomid, later realizing it's only been day 1. :( calling my doctor tomorrow morning to see what he says but has anybody taken Clomid DC1-5?
