Good morning ladies. I have been using these opks this month and today is my fifth day of the flashing smiley face. Anyone use these before and what was your experience? My dates have all changed in glow now, af was supposed to arrive 2/16, now glow shows 2/20. Just waiting for that solid smiley face!! Thanks ladies!!
