ClearBlue Digital Pregnancy Test with no result??

So I'm one day away from supposedly having my period. For the past 3 days I've been taking a pregnancy test every morning to hopefully see "pregnant" on my test. As usual I take the test for my first pee and I do everything correctly. I replace the cap back onto the test and lay it flat waiting for my result. I see it doing the countdown as it always does and once it's in its final counting phase.... It just goes blank. No "not pregnant" or "pregnant" result. Has this happened to anyone before?? The crazy inside of me says "maybe I'm pregnant!!" But the reasonable side of me is saying it's just a faulty test and I just wasted my first morning pee. :(
