I don’t know what to think

Destany

So I collected my second morning urine (I didn’t have a pregnancy test on hand for my fmu) in a cup and took a Walmart cheapie (faint line), took a first response early result (much darker than the line yesterday) and a first response digital but it said no. I don’t understand! My lines are getting darker but the digital says no. Any advice or thoughts? My period is supposed to come in 3 days (hopefully a no show).
