Is it weird?

Is it weird that for some reason i have a strong feeling i could be pregnant? AF is due tomorrow but im not having regular pms symptoms.. Im actually having none. Yesterday morning i went to the bathroom and when i wiped there was like a light brown color piece of super tiny discharge or tissue.. Idk it was weird.. that came on it.. Then later i had a tiny amount of light brown diacharge super thick and creamy.. Usually for my period its liquidy like im about to bleed. My boobs dont hurt im not cramping.. The past 2 weeks no matter how much i sleep i wake up with my eyelids heavy. Im so tired all the time.. But im restless at the same time. I keep getting nauseous when i eat or see something that would normally not gross me out.. I could just be hoping to hard... Any words of wisdom?
