test confused

Okk. So I'm so confused it this normal or am I just hat crazy? I thought I had a box of pregnancy tests in my closet and I pulled out the box and found a test I took on January 19th which was negative then today when I looked at it before I threw it away there is a faint line and my period is 3 days late as of today. Does this just happen to them after while? First picture is from January 19th and second picture is from today from the same test. Am I crazy?
