Flu at 34 weeks?

Ally

I got this bad virus thing my daughter has and it hit me like a bus. I’m worried I’m dehydrated? I’m drinking like absolute crazy but my lips are pale and mouth is constantly dry it’s like I didn’t even have anything to drink at all, my whole body aches so bad, sore-ish throat, I’m having back and belly pain, and last night I was up throughout the night with loose stools I don’t know what’s going on. Is there anything I should be concerned about for the baby? Any steps I should be taking?
