How many flashing smiley days do you get before a static?

I’m using clearblue advance digital ovulation tests and currently on day 6 of flashing smiley - still waiting for my static! I’ve read the instructions so I know there can be up to 9 days before they say to stop testing. It’s my first cycle testing after a rough few months with no period so hoping things are getting back to normal. I’m usually a 31 day cycle :)
