Help/advice wanted

I am not late yet, I am expecting my period this Tuesday(3/24) or Wednesday(3/25). But for the past week or so I have had nausea, sore/ tender breasts to the point I hate my bras, I'm always tired, and my lower abdomen is pretty tender and I get little slight cramps here and there but nothing like Pms cramps mainly when I'm walking. I'm just wondering if I may be pregnant but I would only be a couple weeks if so and don't know if I would really have symptoms yet. Any help or advice would be greatful and thank you. 😊
