What's going on with me?

Marissa

My period is 3 days almost 4 days now late. I took a test this morning with somewhat morning urine(could barely sleep) and I got a negative result but the barely there gray line that I would think is a evaporated line showed up only a few minutes after I took the test no where near the time it takes for the test to dry. what's going on? Anyone ever had this happen before?
