HOLY CRAP!!

so I need some advice ladies! I period started September 16-18. And there was no blood what so ever. It was ALL just brown sludge stuff. Idk how to describe it. It didn't have a bad smell or anything. But along with it I had almost no cramps. I felt great! (I'm usually in the worst pain of my life) but now I've noticed I'm tired through out the day and I can't stop eating. I'm very moody which isn't like me at all. And I feel the urge to pee more. Not anything crazy but more than normal. Can I get any advice on if yall think I'm pregnant or not. Thank you all!!
