Monitor was high for the 6th day in a row today, didn't detect a peak on FMU. I alsoused an OPK on FMU and it was stark white.
Here is the progression the rest of today:
10 - neg
11am - neg
1245 - +++
315 - +++ test line darker than control line
445 - ++++ test line wayyyy darker than control line
815pm (not in photo) - still +++ but not as dark as 445pm

Yes I POAS a lot on my O day - find the progression fascinating.
