So I know the OPK strip detects LH surge right?
My clear blue OPK detects LH and Estrogen right?

So does that mean the flashing smiley is detecting estrogen??

My first day of using CB OPK was today so from reading this morning, flashing is Estrogen and the solid is LH if you’re using the 4 or more fertile days Clear Blue! Smile
