You are having symptoms of
Gastroenteritis. It is a condition in which due to either viral, bacterial or protozoal invasion intestinal mucosa is inflamed causing symptoms like Nausea, Vomiting, loose stools, abdominal cramps etc.
However its not necessary that all symptoms are always present. Usually, gastroenteritis is self limiting and settles down in 5-8 days by itself. However if it's bacterial or protozoal, antibiotic therapy should be taken for 5 to 7 days. I would suggest you to go for stool routine and microscopy test to find out if its bacterial or
protozoal infection.
Suggestion-
Ultrasound abdomen should be done to rule out other problems like intussuseption which mimics gastroenteritis symptoms.
