Cheese Pizza Causes Illness - Pizza Hut,

Ordered a cheese pizza because I didn't feel like cooking. Pizza came around 3pm ate it for a late lunch and then dinner. Around 930 I started to get immediate sickness I had been nauseated and had cramping but thought it was due to other things now it makes since. I can't leave the bathroom and I'm praying my four year old doesn't get sick :/ she hardly ate so I hope not | Symptoms: Diarrhea, Nausea, Cramps
