Every woman is different! Some women may get a positive 6 days before her period (RARE) and others a week after expected period. I would wait a week and test. I'm waiting to test in the next few days myself! Good luck to you.
So 6 days is way too soon. I have 2 boys and last year had to have 2 DNC's, 2 missed pregnancies at about 11-12 weeks. So, I am trying to have a baby!
I would take one 2-3 days before a period is expected, but taking one when the period is due or late is best and more accurate.
