Faint lines and BFN

Amanda

So I have taken a early detection pink and blue dye. Both with faint lines to the eye and when tweaked.

I took an 88 cent test last night that isn't necessarily early detection but I thought it would show up but i don't think I'm seeing anything. My period should be due today or tomorrow usually. Dpo is 14. And I took a digital one Just now and it says not pregnant. What gives?
