Premom OPK charting - help!

Becca • TTC #2, PCOS, on metformin

Below are pictures of my OPKs so far and the graph associated with them. Only the darkest OPKs of the CD are there.. I was taking them 3x daily so I don’t think I missed my surge. Has anyone had an opk pattern like this and gotten a positive?

I ovulate anywhere from CD 19 - CD 32 (on metformin for PCOS). Currently on CD 22.
