Covid has hit the house

my daughter (2) tested positive for covid April 6, my son and I are still no symptoms but my daughter is also asymptotic. If it has hit your household, how long did it take to go between each other in the house hold? I have a trip coming and I’ll be right out of quarantine the day I go. I also scheduled for my son and I to do the drive thru testing this coming Tuesday (week from her positive). This is all just confusing and stressful.
