Taking test wrong?

Would taking a pregnancy test wrong be the reason it could be negative? I just realized I haven’t been peeing on it with the result window facing away from pee stream. AND I flipped it/laid it upside down while waiting the 3minutes on accident (I try and avoid looking at it completely until it’s ready because I’m nervous!) Should I retest or does it not make that big of a difference. I was supposed to get AF yesterday but she’s not in sight 😏🤞All negatives so far though..
