Faint line or no?

I used a $store brand and it came up negative twice. Then I took a rite aid digital early response and it said the dreaded words "not pregnant". But for hahas I popped it open and I could swear there was a faint second line! Is that normal for the digitals or could it mean I tested too soon. AF is due Wednesday. All advice is welcome please!
