So confused???

So my clear blue advanced has been showing a flashing smile for the last 4 days, so high fertility. I also use my easy@home strips during the day to check. Well I got what I thought was a positive on Saturday afternoon (see pic). I figured I'd see a peak clear blue either Sunday morning or this morning, but it's still a flashing smile. And all my other strips have come back much lighter than my possible positive.

Was it maybe a fluke? Or should I mark that day as a positive? My cervix has definitely been feeling high soft and open, but haven't seen ewcm just watery or maybe very very light ewcm.
