Could u take a 3rd test? Make sure you are testing same times in day so your pee is not diluted? Those would be my first steps
I agree, its best in the morning to test and try again in another day
Test tomorrow morning first pee.
It could be a chemical pregnancy but could also be diluted urine, although less likely given the 3 days.
