question: I have taken several different brands of at home pregnancy tests. All of the blue ones (EPT, Equate, Clearblue) keep coming back with a faint blue line. The pink ones (first response, dollar tree) keep coming back COMPLETELY blank. I even splurged and bought a digital test because it supposedly will give a pregnant or not pregnant response... I got a picture of a book - both times. I m so confused... am I pregnant or not?
