Faint positive easy@home ?Progression

So I have been taking tests daily since 2/20 the line is still faint on the easy@home and has barely darken over the past 3 days. Also faint line on first response strips. But FRER I have positives but not significantly darkening over the same time but they also are not getting lighter. I seem to get darker positives in early afternoon vs FMU.
