First time using blue dye? BFP or no?

I usually use pink. This time I just so happened to grab a blue. I see a very very very faint line there. Anyone else? AF due 10/1.  Fiancé & I have been trying on and off for a year now. Not preventing for 3 years.  Newly engaged. Getting married this month. We're more than ready for a little nugget!
