Letrozole and ovulation tests

Bree

So my doctor just prescribed me on letrozole 2.5 cycle day 3-7, and to come back in 8 dpo for progesterone testing.

I purchased the clear blue ovulation kits and I’m confused on which day is the ovulation day, is it the blinking smiley or the solid one?

Also, I ovulate on my own my MD prescribed this to help my eggs as I have pcos, has anyone had luck with this? I know it’s a process but I’m worried that it’s not going to work.
