When will I ovulate? After taking my first cycle of letrozole

Hi so this cycle I took my first round of 5mg letrozole from CD 2-6 so I'm currently cd 10 so I tested for ovulation as I heard you can ovulate earlier, so I took a ovulation test I know it's not positive yet that's not what I'm asking as iv had blazing positives before on cycle day 14/15 as I ovulate every month on my own, but my fertility Dr prescribed me letrozole to see if it helps us. So yeah from today's test when do you think I will ovulate?? Thank you I'm gunna upload yesterday's test to show it against today's test!!! Thank you

This is yesterday test!!!

This is today's
