Vomiting & Diarrhea

Hi ladies I am 28 weeks & 3 days, last night at 11pm I started having diarrhea and the cramping, vomiting started at 3 this morning , I tried drinking orange juice and I puked that up also, I just drank 3 sips of pineapple juice and had 3 ice cubes and the rumbling cramps started up a little with slight nausea. I'm laying down trying to take it easy but I don't know if I have a stomach virus or what? I'm considering drinking ginger ale but afraid that won't stay down either. Has anyone else experienced this or know what I should do? Call my Dr.?
