Is this normal?

I don't even know if im pregnant yet or not bc I'm only a day late on my period so far but I've been very nauseous along with other symptoms. Is it normal to be nauseous quite a bit if I were to be pregnant? I'm nauseous almost all day & after I eat usually. It's been going on for about a week or so. I keep thinking maybe I'm just sick bc yesterday I started having a stuffy nose & sneezing a little but I've been nauseous for about 10 days or more
