Hoping my negative is negative

Leslie

So I usually get my period 3 or 4 days before I’m expected to according to glow. But I now it’s saying I should be getting it tomorrow and I’m not having any of my usual menstrual symptoms. Instead I’m having symptoms I’m never had before, like Mood swings and sensitive smell. I took a test yesterday and it came out negative. Could there still be a chance? Has anyone gotten a false negative before?
