Stored Pee Pregancy test. Is it accurate???

I took a pregnancy test but I didn’t have time right there in the morning so I stored it in a water bottle that I emptied. I made sure there was no more water but it had tiny weeny drop on the side surfaces that I could not get ride of no matter how much I shakes the bottle. Can that affect the results of my pee? I got a negative but I scared it may be a false negative due to tht
