So I have been using the Clearblue Advance digital OPK for a month now. I got 5 days of flashing smiley faces, and then I got the empty circle again. I never got the solid smiley face. Did anybody else have this issue? Is this a sign that I’m not ovulating? Anything will help. My husband and I have been TTC #3 since June, and I know that isn’t that long but it still sucks seeing the negatives.
