I was surprised when glow indicated a fertile window 3 days after AF. I have been using ClearBlue OPK for the past 9 days but it shows a flashing smiley in the last 8 days. Have I missed my ovulation this month? I have not received a peak opk and no ewcm. I also use Ovia and Ovia show that I just entered my fertile window about 3 days ago.
