Can you feel Braxton Hicks in your mid stomach?

I’m not sure what it is? I could be just be getting stomach cramps from like a stomach virus or something? But I keep getting these pains in my mid stomach area all the way to my mid back and it hurrtttsss. Almost feels like I can’t breathe. I’ve been nauseous all morning. I feel like everytime my stomach hurts, it pushes and makes me want to puke. I’m just not sure how my back pains tie in with stomach pains? I’m 33 weeks pregnant.
