Is this normal? In so much pain

Brianna • 20 years old & have a rainbow son after my first miscarriage 🌈
So I'm almost 6 weeks pregnant, and it just started today. I guess I waited to long to eat or something idk. But I just got this extremely bad stomach pain. It's like naseua and pain at the same time. It fluctuates, keeps coming back then settling. Every time I eat something like water or crackers it brings the pain. It hurts so bad .
