opk no flashy smiley

Lauren • My fiancé and I have been TTC for over 2 years now! Trying to Remain positive. Good luck to all of you lovely ladies ❤️
Hey ladies, I've been using clear blue dual hormone OPKs for the past 3 or so month and I never seem to get a flashy smiley face it goes straight from the blank face to the solid smiley. Is that normal? 😿
