HELP! PCOS, Letrozole 2.5MG Round 2

Hello everyone,

So on my first cycle on Letrozole 2.5mg, it was obviously a fail which brings me here to ask you all...

On my first cycle, we had sex everyday in the fertile window and skipped ovulation day.

This glow app is telling me that the most important day to have sex is the day before ovulation because you just have a higher chance.

But, I've always heard and have been told to never miss ovulation day either!

We are doing this every other day and making sure we get it done on the day before, but should we also do it on ovulation day?
