HPT question

Julia
I've been testing every day since 7 dpo.  I'm now 11 dpo and AF is due 5/27, still not even a faint line.
I was wondering if any of you who were testing every day got a positive result for the first time only 1, 2, or 3 days before AF, or even after AF was due.
I'm just wondering if it's realistic to still have high hopes that I'm pregnant.
Thanks!
