Maybe pregnancy???

I don’t know if this is the right place but I had my period last month but for the past 2 weeks I’ve been extremely nauseated especially by the smell of food. Went out to eat and vomited everything I ate which is not normal. Also been more tired then usual. Could I be pregnant ? I haven’t taken a test I just didn’t think being nauseous would come this early especially since I had my period last month. Just so confused right now. Has this happened to anyone else?
