Ovulation test

Jodie 💗🌟
Advice please... I been doing the clear blue ovulation tests for 4 days now... First one was a black circle and I've had my flashing smiley face for 3 days now. How many days did others have a flashing smiley before getting the static smiley??? According to the app today is my most fertile day so I thought I would get my peak today but I got a flashing?!?
