Helpppp

AF was due 7/27, 6 days late now! What would the chances of getting my period be at this point? I haven't tested yet as I want to wait a week so tomorrow morning I will be testing! And to be honest I'm scared to test as I don't want a negative result.. We've been trying for just over 2 years and our anniversary is coming up in a couple weeks! So I'm really hoping this is it!
