22w pregnant, low belly pain

This is my first child so I may be asking stupid questions — therefore, pls be considerate of your answers :)

I haven’t felt the best today. Little nauseated here and there, kinda lethargic. Still getting used to the baby moving around because it almost takes my stomach when she moves suddenly.

I ate dinner about 30 mins ago.. now my lower stomach (top of my panty line/3 inches below my belly button) is sort of cramping.. or she may be curled up in a ball right there.

Obviously I’m not sure what contractions/Braxton Hicks feel like so could someone kinda guess what could be going on?

Maybe I just need to poop? 🤦🏼‍♀️😂

Anyways, any advice will help
