Faint line or evap?

I am 7 dpo and I think I see a faint line. Not sure how to edit the photo like I see others doing to confirm whether it's actually pink...I also poured water on a second test (I know, I know) and there is no faint line like that. Any help is much appreciated. 
Okay. I added a negative photo on the bottom.  The top is the water test, bottom is the real deal.
