Food poisoning/stomach flu....?

On Tuesday night I had some chinese food (fried rice and vegetable spring rolls). That night I started getting REALLY bad gas pains and by 3am I literally threw up the vegetable rolls(not the rice) or anything else I had eaten that night. I have had loose still the past 2 days. Since than im still nauseous and I keep burping everything I eat for hours. Do you think this was food poising from the chinese or a stomach flu? I have NO fever.
