took 3 test an all came back with a faint line

Drea
I've been super hungry lately like every 3 hours or so, I have been cramping for 3 days and I never get cramps often before my period n AF  isn't due until the 9th,  could this be a positive test ? First picture is of this morning(2 days before AF)and second was the day before (3days before AF)
