Is it normal?

I was sick Friday night into Saturday morning. Roughly from 10 at night until about 7 in the morning. Normally, I would be sick and than after a day be fine but I’m worried bc of the stomach pain. I had really bad stomach pains for two days before actually getting sick. And now it’s two days after being sick and I’m still getting stomach pains like I did before, just not as constant. I feel a little nauseous at times but not like the “I’m about to get sick in the next few seconds” type. I still have no appetite whatsoever. Drinking anything aside from Powerade or those types of things, as well as gas, still cause discomfort and cramps. Is this normal or should I get checked out just to make sure?
