Question: 7dpo Symptoms

I’ve been having a lot of symptoms and I’m wondering if It could be a pregnancy symptom. I usually don’t nor mail feel this way even when I get my period I don’t feel this way. I’ve been felting nauseous, cramping in my back and lower abdomen, I even had cramps in my lady area, and I’ve been feeling Constipated as well, and had hot flashes like been super hot and I usually never am I’m always freezing and you can catch me with a blanket anyway but today I made my house as cold as I could and was still hot but not like a fever in anyway.
