Faint line?

I previously (2 days ago) took a Clearblue test and many of you saw a faint line, so I decided to take a First Response. My period has been late by 14 days so far. The first three pictures are of my pregnancy test; some have been tweaked to see the line easier. The fourth is a picture of my cycle with green indicating times I’ve had sex using the withdrawal method. Am I just paranoid for seeing a faint line? What do you guys think? Positive or negative?
