Evap or BFP???

One on the bottom with the darker line was yesterday’s and looked the like one on top. Heard that if you add water to an old test that the evap line would disappear but this one actually got darker (as pictured). I’ve been planning on taking one a day to see if lines increase and Aunt Flo is supposed to come on Tuesday.

Anyone know what evaps look like?? I’ve never experienced them before or used these types of tests.
