Are you able to tell if you’re nauseous because of hunger or just nauseous??

Just started week 6 and having nausea but it’s confusing cos I’m not sure if I’m nauseous because there’s no food in my stomach or it’s just nausea 😩 felt better after eating something light. I didn’t feel hungry though but it was many hours after lunch. Does eating help all the time? #firsttimemom
