Does it matter how much urine you put on a pregnancy test?

I got the 6 days sooner test and i took it yesterday and i dropped like a drop of urine which i saw on the test bar that it was wet i feel like i didnt put enough it was my first time testing. Period is due tomorrow and it gave me a negative should i believe the test? I did not use a cup i threw away the instructions on accident this is why I’m asking here.
