On day 3 of missed AF neg preg test

Does this mean I’m out for good and should suspect my period or should i test again on Monday? According to glow i should of started on the 10th and if i don’t get today, tonight will be day 3. Normally glow is pretty accurate on my dates. I just took a test and it was negative. Idk i just have a feeling af isn’t coming but maybe she will. So should i throw in the towel or test again on Monday or Tuesday if i still haven’t started?
