Once again this test lets me down.

Ugggg... Second time I have used the ClearBlue easy pregnanacy tests and the digital screen doesn't turn on. The very first test 2 months ago, no problem! So I know I am doing it right.... The second and third this month, NOTHING!!! I am sorry, but I am done with your brand. This is the most frustrating thing in the world!!!! Now I wont know until I get to buy some tests AFTER WORK.... Glad this isn't a life changing possibility or anything......
