So yesterday I posted a pic of a dollar tree test , I knew it would be negative but wanted to see I swore I seen a line in the time frame but majority of people said no 3 people said yes

Today I picked up a test quick from the store not knowing it was blue dye and in the time frame again I see a faint line, but most definitely BLUE @ 10 DPO it wasn’t FMU either. Still have 3,4 people saying evap. Will a evap show within 3 minutes of my test? This is why I always use pink dyes 🤦🏻‍♀️ I have another blue dye and my sister will bring a pink dye tomorrow morning.
