Bad Stomach Cramping?? Help

Kelsi • Under every pretty face is something complicated ✨💚

This is my 3rd pregnancy and I am 6 weeks pregnant and I keep having bad stomach pains/cramping after I eat something or sometimes it just happens on it’s own. It kinda feels like gas bubbles that hurts really bad but also feels like knives being stabbed into my belly. Does anyone know how to stop them or what precautions to take so I can get rid of the feeling? Or if there’s any foods I should definitely not eat? Thanks.
