πŸ›‘ Line on pregnancy test disappear? πŸ›‘

Hey all! Is it normal for a very very faint line on a pregnancy test to not be visible roughly 6-7 hours after I took the test?

The very very faint line showed up within 3-4 minutes of taking the test, but 6ish hours later I came back and the line isn’t noticeable!

Is this normal!?
