Confused 🤷🏽‍♀️

Last night I posted a poll with a blue dye test I took, it looked like a faint positive. I took the same test this morning and I think I see a line. I’m not familiar with blue dye as I prefer pink, but blue is all I had. I will retest with my last digital on my projected period date 5/31 but does anyone see anything on this today’s test? Anyone use this EPT brand before? Are they known for evaps? TIA
