20 days of Flashing Smiley Face.....

Ladies - please help. I started using a ClearBlue Digital test last month (for the first time). I have pretty regular periods - usually a 24-26 day cycle. I started testing on CD6 last month and had 4 days of the empty circle. Got excited when I got the first flashy face, but 20 days later I'm so bored of that stupid face!!! My period came a little early this cycle (like a week) and I kept testing all the way through - and it was still giving me the face. It's still giving me the face now - and I'm on CD6 of my next cycle....
