Is this a positive or evap line

Sa

I took a test this morning and it didnt show up immediately so i went on about my day and thought it was negative. I went to use the bathroom and took another look and I seen a faint line. So I thought maybe it was something that happens to test that have sat too long after taking them. I took another one to check and i got the same thing its just not super dark. I was supposed to start my period yesterday. So I'm posting this pic. Plz give me some advice and opinions. I used mom med test strips instead of wasting money on overpriced test. So this is my first time using these. So idk if anyone on here have gotten a false positive off those test or not.
