When did you ovulate in your cycle after taking Femara/Letrozole?

I'll be starting Femara on Days 3-7 and it is currently Day 1 of my cycle. When did you typically ovulate? Also should we BD every day or every other day? There seems to be mixed reviews about timed intercourse and its frequency. I won't be having a trigger shot this cycle but, I will be monitored. I also started my cycle up with Provera and it took 9 days after the last pill for me to start my bleed. Doctor assumes I have PCOS and borderline Hypothyroidism. Idk if any of these factors matter but, they just are what concerns me currently.

Basically:

When did you ovulate when taking it on cycle days 3-7?

What is the frequency in which you BD?

Do any of these other factors effect when I may ovulate?

Thank you so much in advance for all of your answers! Good luck and baby dust to all who are trying!
