Evap?

Alyssa

Took the top test this morning with fmu....didnt see anything after a minute so I left, forgot about the test. I'm still 3-4 days away from af, so it's a little early and I didnt expect a positive. Came back a little later and saw that it did have a faint line(dont know how well you can tell from the pic but it is pink) so I took another one(bottom test)... but I dont see anything. Could it be because the first test was fmu? Or do think its just an evap? The only reason I want to doubt its evap Is because i have 4 other tests i taken before those too amd they are stark white, no evap at all. Trying not to get my hopes up though!
