Evap lines?

Ba

I’m EBF X5 months. No periods yet so try to test every so often. We were ttc for 10 months for this baby and I never saw an evap line on a Walmart cheapie. Could this be an evap? Whaddya think? This wasn’t FMU. It was around 11am. I tested today with an equate early result blue dye and its stark white but I’ve heard Walmart cheapies are more sensitive?
