Clearblue Digital Advanced

Hey everyone! I’ve been using the clearblue digital advanced ovulation tests for the last couple cycles. The last 4 days I’ve had a flashy smiley (high days) and this morning I had to open a new box and got a blank. Has anyone had this happen? I’m wondering if I actually did skip ovulation, or if I’m wasting my money on these kits since this happened with a new step and tester (for those who haven’t used this- each box has its own test reader) so it knows this was the first one.
