Can someone help me understand!

Took a hpt at 5:55AM. Vvfl at 3 minute mark. BUT after the 10 minute mark of reading the test, my line got darker... which obviously after the allotted time, you ignore it but just trying to reassure myself that y’all see the line on the first test.. maybe my line just got darker? Or it’s an evap like and a BFN??

1st pic is at 3 min mark

2nd pic is after 10 mins. (I think 14 mins)
