10dpt is the ideal time to begin testing however it can yield false negatives due to late implantation. I understand the stress however you're doing more harm to your body and potiential baby than good by being super stressed. Try to relax by thinking of people/ things in your life that make you happy now. Hopefully this will ease some of the tension. God bless you and SSBD
my first BFP was day 8 but everyone is different.
only test tomorrow if you have prepared yourself for either result....some folks are more stressed by repeated testing, some are more stressed by not testing....
good luck!
