Stomach bug

El

I'm 25 weeks pregnant and feeling like I have a stomach bug, stomach cramps, diarrhoea, vomiting even after water. Is there anything I can do to help it settle? I did think it was morning sickness at first as I've always had that but then came along the other symptoms too, I'm not getting any relief. Feel too hot and super thirsty eventhough I'm sick after fluids 😩
