6 weeks pregnant

Hey I'm 6 weeks and two days and I've been having to doo doo all day it would come out watery and some would come out regular than I would get this gas feeling in the top of my stomach it's like a cramping gas feeling . And I would get nauseous to like certain smells and the thoughts of certain foods. But the main thing today was having to poop a lot I poop  at least 7 times today and like I said here and there I would get this cramping gas feeling in the tip of my belly would could this mean ??
