Kinda bummed, but haven't lost complete hope

So I had a 2 pack Equate 5 day sooner hpt (blue dye). I took one on Saturday, about 10 dpo and in result window was white as white. This morning, about 12 dpo, I took the second one and within 5 minutes I see a very faint line in the result window. Went to work, really hopeful and excited. Than, I start reading about blue dye test and them being pretty notorious for false positives. I wish I could leave work already :(
