HPT Question

J. • Baby Girl Due 10/2021 via FET
So I just took a test at 12dpo. I used the bathroom and for whatever reason decided to take the test maybe 15 mins after. It was barely a tinkle and got a BFN. Do you think I'm out or is there a chance it could be positive with a 1st morning pee tomorrow? I'm getting so frustrated with TTC. :(
