Could I be pregnant?

If I am only just over a week pregnant, would I still have pregnancy symptoms? I know it’s early but I just feel really tired and sick when I eat so I don’t know if I’m coming down with something or I could be pregnant? I haven’t took a test yet as I’m not due on my period for another 3/4 days. Would just like some advise first and what other people think🤷‍♀️❤️
