BBT chart help please girls

Hello all, my first post here and I need a little help.

I’m pcos and ttc for 22months. This cycle I am on letrozole and currently cd22.

I had been using OPKs but either there was no surge or I missed it.

From the chart, with the dip and the rise, does it look like a big enough rise to be ovulation? Is it possible the OPKs could’ve missed it?

Thank you all
