Ovulation after Letrozole

J. • Baby Girl Due 10/2021 via FET
How long after taking Letrozole alone do you ovulate? I started my first round on November 16 and last pill was the 20th. I saw the Dr on the 24th she said my eggs looked great & to be for the next 4-5 days. From those dates when would you test? TIA. This is all a bit confusing. I appreciate any feedback :)
