I have recently been trying to track ovulation using the Clearblue digital test. Last Wednesday I started and I got a blank circle ⭕️. I checked again on Thursday (a week ago today) and I got a blinking smiley. A week later it’s still blinking and I have yet to get a solid. Anyone else experience this? What does it mean?
