Faint line on FRER, not pregnant on Clear Blue Digital

Took this FRER and easy@home strip last night. Both are squinters, but I swear I see a line. I took a Clear Blue digital and it says "Not Pregnant". How disappointing is that? I am hoping I am just so early, the CB can't pick it up yet. How many days after a vfl on A First Response did you receive a positive result on the Clear Blue Digital ?
