Faint? Not sure

99 cent store/u check brand, which I've used a zillion times before. I'm 9dpo... Took the test and it looked like it came up neg after 2 mins. Washed my face, brushed my teeth, and looked again and I swear there is a faint line now!! I've never ever had an evap before on this brand but I'm not sure if it's there or if it's an evap since I'm not sure how long I took before looking at it again. What do you all think?? This would be my rainbow baby!!
