Fever, Headache, Nausea, Fatigue, No Appetite, Diarrhea. Causes For Symptoms?

Hi, I think I may be working through a stomach virus, but I wanted to be sure and to check about what may be too long for certain symptoms. Here it goes! Saturday, I had a fever, pressure behind my eyes, headache, nausea , fatigue , no appetite . Sunday: no fever, nausea, diarrhea , ate bananas, fatigue Tried to eat scrambled eggs , but this intensified the cramping. Monday, no diarrhea, no fever, bananas, applesauce, toast, intense cramping in the evening, fatigue. Tuesday, today: diarrhea all morning, less cramping, a little more energy but not energetic, ate rice, bananas, apple sauce, rice, minced veggies, but still not much appetite. Any thoughts? THANKS!
