is this a faulty test???

i took this test first thing in the morning but didn’t wait to see the result because i was running late. when i got home i looked at it and this is what i saw. i know that a positive result will stay for longer, but i also know that you’re supposed to check the results within a certain amount of time. i am also late. i’ve never seen the line look like that no matter how long it had been since i’ve taken the test so i was curious if anyone else had seen a line that thin and if it maybe means that it had been too long.
