Am I ovulating?

Currently CD 8 I have PCOS so I’ve never been certain I’ve ovulated but it’s always been around CD18. I am on my second round of letrozole 2.5mg day 3-7. Took my first Clearblue advanced test this morning and got a static smiley on the first day of testing.

Took a normal Clearblue and got this.

I had a longer period this time (7days) and am still lightly spotting today. How accurate is it that I’m actually ovulating? Having a hard time believing it!
