Pregnant?

I’ve taken many pregnancy test before (ttc and pregnancy scares before ttc). I usually use the little Walmart brands that are 88 cents. Usually they come out negative, I keep them a few days and they stay negative. No evap lines or anything. I tested on 5/28 and 5/29. They both had vvvvfl and darkened after they dried up. Am I pregnant or did I just happen to get 2 evap liens on 2 different test on different days?
