Stomach flu?

I'm 6w2days and my god I feel like I'm dying.. Puking constantly ginger ale is now just horrible.. The diarrhea is killing me... The nausea was almost gone until I didn't eat anything so I got really sick and nearly burned my throat from the acidity from the ginger ale... Could this be stomach flu??
