Clearblue digital OPK question

Jamie

Hi ladies I just started using clearblue digital ovulation tests and I’m a little confused. The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I should have ovulated Tuesday but I am still getting a flashing smiley face on the test. If I ovulated wouldn’t I have gotten a solid smiley? The test has given me a flashing smiley for 6 days now. Is that normal?? Please help!! Thank you
