Inside of a digital pregnancy test. Need advice!

Jill
I took a digital pregnancy test on Thursday. It was 13 days past ovulation. It showed not pregnant. Well 3 days later (today) I thought to myself ... I wonder what the inside of a digital pregnancy test looks like! So as gross as this sounds, I went to the trash and got the used pregnancy test. I busted it open and this is what I found.... is the line so faint it didn't register? I'm too nervous to take another right now of a false negative and disapointment.
