The Return of the Flashing Smiley!

Here I am on day 12 of my cycle, knowing it's too soon for me to ovulate. I bought the ClearBlue digital advanced kit and decided on CD6 that I'd try it out, what the heck. Of course it's negative. So on CD 7 I try it again and get a flashing smiley. I was so confused, but continued to test every morning. 6 days later and I get greeted with a flashing Smiley every day. The little guy is getting annoying now. Anyone ever experience 6 days of high fertility with this brand? I'm also testing with cheap strips in the afternoon and they're as negative as can be. Losing faith in ClearBlue this week.
