In my experience, and that of a few friends, LFDs worked great for our first infections but seem to be fair less sensitive for second and third.
I had COVID over Christmas and only had a faint pos test on day six or seven but was neg for other days. Same for my wife. Total guess but I wonder if you generate/replicate as much of the virus when you're on your second or third infection...
Interesting but very much not scientific. Just know a bunch of people who have tested positive for COVID but only barely in terms of lack of bold line recently.

Personally I'd assume that you have COVID.
