Late period and negative tests

So my period was due yesterday, and it still hasn’t arrived. My period is never late. I had an accident in bed about a month ago probably less which leads me to believe I may be pregnant. I took a test the day before my period was due and yesterday (the day of my missed period) I have been peeing very frequently, I have been sneezing so much! (Idk If that relates) and my hunger took a massive spike about 1/2 weeks ago (it isn’t as bad now) what should I do?
