HELP- Clomid!

I start a very light AF on Monday. Light pink, but consistent. Stayed very light on Monday, and Tuesday, and Wednesday. I occasionally saw red- but mostly light spotting. I called a nurse st my OBGYN... and she said I should have counted those days as day 1-3.... therefore I should have been starting Clomid on Wednesday. Rushed to the pharmacy and picked it up.... started Wednesday night.

Now- Thursday morning I get up and I am having a “real” period. Heavy flow- normal for me. Did I screw up my days? What will happen if I didn’t truly take Clomid on days 3-7??
