Talk to Pediatrician on White Stool Color

My 4 year old has passed stool twice in the past 2 days and both times it was white. I didnt think it was anything serious until I googled it and now it says that it might be due to some serious underlying medical condition. She is otherwise perfectly fine. Eating playing and doing everything normal. What can this be?? Her food intake is absolutely normal. Not eating much junk food either.
