Is it normal?

First time young mama (21) pregnant here. I am 6 weeks and was wondering if that feeling of constant nausea is normal. No matter what I do, even if I eat, don’t eat, rest, I just feel nauseous. Is that how your supposed to feel or normal? I know every pregnancy is different i’m just asking for a little guidance. No vomiting, but have a couple times only because the food just didn’t sit right with me. Do you have any suggestions on what to eat too? I do eat it’s just thinking about it and then eating it makes my nausea worse. Sometimes I can keep it down, if I don’t I throw up a little bit. Makes me cry because I have never felt like this before :( I know I’ll be okay I just want some help. Thank you 🥲
