Do tests deactivate positive?

These pictures were about an hour and a half after I took the test. At first it was playing tricks on me but after 20 mins I came back and it looked like there was a very faint line. I’m only 24 days so I’ll obviously retest but wondering if they will look positive even if they’re not after awhile. This ain’t my first rodeo, we’re ttc #3. Maybe I’m getting my hopes up?!
