Is the test right ? Am I pregnant ?

Magdalena
Hello , I'm so
Nervous ! 
I expect my period today !  Two days ago I had a brown discharge really dark . It was just a little . 20 min.   Ago I made
A test . I'm attaching a photo . Is it possible the test to be wrong ? Has anyone had a situation like this ?  I have just a
light line  . Has anyone had false possitive test?
