Positive or evaporation line?

Hey guys! So my period is due today and so far no signs of it! I took a test yesterday morning and within like a minute it looked negative so I threw it away. Well about an hour Later, i was getting something from the trash and my test looked like this. Do you guys think it’s just an evaporation line or a faint positive? I am assuming it’s an evaporation line so I plan to retest in a few days with a pink dye or digital test if my period doesn’t show. Just wanted to know your thoughts.
