How long does everyone wait?

Bianca • Momma of one son👦🏻, momma of angel baby👼🏻, and momma of fur baby🐶, hoping to be momma of rainbow baby soon 🌈❤️

How long does everyone wait after taking their first test to see if the second line gets darker, I know you’re supposed to wait 2 days butttt I also know if you all are impatient like me you test sooner and if you did test sooner than 2 days did the line get darker before the 48 hours?
