Good Morning Ladies Clearblue question???

Shay
Is it possible to miss Peak Fertility on the Clearblue Digital Ovulation Kit and just continue to get flashing smileys even though you are O'ing? I had a few symptoms this week, although I'm not sure if it was in my head.  If you have used clearblue advanced ovulation kits how long do you normally see that flashing smiley?? Have you ever missed your ovulation day??
