Weird ?

My period is supposed to come in 4 days. I say supposed bc it never comes on the same day every month, either a few days early or later. Anyway, I have a terrible headache, I’m hungry as hell, and really tired. But usually, w my period this close I’ll have real bad cramps but they’re pretty minor and I’m not having discharge. Am I okay? (When I wipe there’s nothing out of the ordinary but I can smell my period coming). 🥴 help?
