Stomach pain

so the past couple of days my stomach has been hurting. When I wake up in the morning it hurts really bad like someone is twisting around my insides. And it will go away then it comes back and it feels like I really need to poop but I go to the bathroom and I don’t have to. It hurts pretty bad and I have been feeling really nauseas and just icky lately. I don’t know if I’m getting sick or stressed out or what?
