OPK Question- Has anyone taken the Clearblue Digital OPK and get the flashing smiley for several days and never get a solid? Today is CD17 I’m going on day 5 of flashing smiley. This is a first for me I have never gotten a flashing smiley. It’s always just a circle. I started testing CD12 and it was just a circle. My app says tomorrow should be ovulation day but I got the flashy again today. When I eject the stick the two lines look very similar but can’t tell if I’m there yet.
