Mrs P you crack me up! I thought I was bad OK, so in my last possessed cycle (when I say possessed I mean with the POAS, lol), I got the following results :

3dp2dt - obvious faint positive, that was the trigger (I was bored and did it for fun to see if the trigger was there )
6dp2dt - line still there but barely visible, I took it as a negative (probably an evap line)
8dp2dt - line definitely visible, I remember it coming up within seconds
9/10/11 etc dp2dt, line getting increasingly dark.

So I'd day it's a very positive sign, sounds like a BFP to me hun!!!
