Really frustrated. Bfn...?

Tammy • Me and my DH have been TTC for nearly 4 years now. We have 2 beautiful children already, a boy and a girl, and would love one more addition:-)
I am 7 days late with AF. This is pretty unusual for me. I took a blue test and had a faint positive but I think it was an evap cause it took almost an hour to show. Took a Frer comfort with fmu today and a bfn? I thought I saw something but I look now and pretty sure its nothing. Feel free to tweak if you see anything. After 3 years I thought for sure this was it. Same test just always take two cause one usually ends up blurry
