Hi, I Am A 15 Year Old Girl And Yesterday

Hi, I am a 15 year old girl and yesterday and today I got a iced latte at dunkin donuts. today I heard a girl saying that she got food poisoning from dunkin donuts and I looked up some symptoms and I'm not sure if I have food poisoning or a stomach bug. My symptoms are severe nausea, dizziness and lightheadedness, a mild headache, moderate diarrhea but no fever or vomiting. my symptoms started shortly after I drank my coffee yesterday then I didn't notice them until I drank my coffee today. what are your thoughts?
