What is the best pregnancy test?

I’m 15 dpo today going to take a test, I need answers. I’ve been to assured pregnancy test (dollar store $1) onessince 13 dpo and they look negative but then maybe faint lines or evap lines. I just can’t tell with them. When I held them up to a light i see a second clear line, I’m just confused I’d really just like a yes or no answer? I’m one day late for my period so far is that far along to get an answer at this stage !! I’m going to spend the extra money on betterbtests if that will give me the answer I jeee thanks everyone !
