Positive Pregnancy Test Question

With my first pregnancy, I used a First Response Pregnancy Test. I still have it to this day, and it looks the same as the first day I took it, almost 5 years ago.

With this pregnancy I used an E.P.T. Pregnancy Test. It came out positive on Feb 12th, a huge bright blue line. As the days have passed, the line has gotten duller to where I can barely see it now.

My question, is it normal for a test to fade? Should I take another test? Am I being a nervous Nelly and worrying for nothing?
