Charting with advanced clearblue and bbt

Full disclosure, i have PCOS but for the past couple of cycles I definitely ovulated and been having regular cycles.

Thought I would take it up a notch and started using the Advanced Clearblue OPK.

First day I used it, it was "low", no face. Next 2 days I got a "high", flashing smile. Low and behold i got a "peak", static smiley that has stayed on for 2 days.

Question: do i put those 2 days as peak or just the first day?

My bbt hasn't risen yet but i have been so anxious watching for the shift to confirm ovulation.

Glow shows I did, but FF doesn't unless i change the settings...didn't have to do that, as it was clear that I ovulated.

I have been on on 2k metformin and 2nd month with Ovaboost...

(Just learning to check my cervix and cervical fluid, and still unsure about continuing)

Any insight would be helpful!
