Is AF here early?

I’m 7DPO and I normally have a 33 day cycle. Last few days I’ve been feeling a little light headed, nauseous, sore breasts, generally achey, hot flashes, I even had a nose bleed today - first in a long time (all of these are not my normal PMS symptoms) then today come home and had blood when wiping. If this is AF arriving that would make my cycle 28 days this month. Do we think there’s a chance of something else going on or is AF just messing with me showing up early? 🤷🏻‍♀️
