NOPE

So I bought a 2 pack of Clearblue Digital pregnancy tests. Both test show a book right away. They didn't work at all. I followed the instructions. I'm pretty upset with this "99% accurate" test. They were not expired and were not expected to expire until 2017. That's money flushed down the toilet. When I was pregnant last time I used a dollar tree pregnancy test and got a positive right away. How can a $1 test be better than these $14 tests?
