Knot in stomach

Maria

I'm a Houstonian so I don't know if it was that crazy ass World Series game last night or my pregnancy that has my stomach feeling so weird. I haven't been nauseous at all but sitting here at work and my stomach feels like there's a knot in it or like someone just punched me in the stomach. It comes and goes every few seconds. Anyone feel any knots in their belly? I'm drinking a ton of water like always.
