pregnant by strips NOT pregnant by ClearBlue

I test with both ClinicalGuard and EasyHome strips, both showed a faint second line. But when I used the Clearblue digital it showed Not Pregnant.
Heartbreaking!
Update: use ept early test tonight (I know I should wait.. guess I just can't help myself...) could you help me read my test? I'm stressful...
