Tmi but need opinions

So I'm due for my "period" late this week but I'm irregular so it's kinda a guessing game. For the past few weeks I've been very nauseous most days, some more then other. Some days I'm not hungry at all and some I'm always hungry. My taste in food has been weird lately. I've been cramping, I'm kinda bloated and my lower abdomen is kinda hard. My backs killing me and I'm always tired no matter how much I sleep. Idk if my nipples have darkened or not tbh but ik my nips are a little sensitive. I just recently went to the bathroom and wiped and found alot of thin-ish white discharge. More then usual.

Could I possibly be pregnant? I'm going to test asap.
