6 year old daughter said her belly hurt Thursday night at around 11 pm then fell asleep for the night. woke up had breakfast said she felt better and went to school, came home said she still felt ok and had supper, fell asleep right after supper for 4 hours then woke up. then couple more hours later said belly hurt again and now wont sleep says it feels like when she has to puke but comes and goes, belly is bloated and when I pressed on right bottom side she said it made the icky feeling worse when I pressed. she will not sleep now, she has no fever and has not vomited but did have mild diarrhea, but has continued all night to drink water. no other symptoms have been noticed or have appeared. Chances of a appendicitis?
