OneStep Pregnancy Tests

So I have been testing with these tests for the past few days, first and second photo were a day after each other, then I got two complete negatives and then this morning I see another faint line. I really don’t know if I am pregnant or not, I know it’s still early as I haven’t missed my period yet, I have a crazy feeling that because these are cheapy tests that they’re just so prone to Evap or indent lines and that’s just what I’m seeing!!! Any of you guys experience this with these tests? Please help!
