Evap or positives??

What's the chances of getting two evaps from the same brand of tests (clear blue) but the tests did not come together and were bought at 2 completely different stores. I got 2 faint positives and they look like they could be evaps but I'm not sure?? This is the first one i took. The second one i took was taken 6hrs after this one but on the same day & it was even more faint but still a solid line. So are these positives or evaps?
