30 weeks

I’m 30 weeks and for the past 4 days I’ve had diarrhea and felt extremely exhausted. Today I’ve been nauseous and having horrible gas pains and still diarrhea. And now I’m getting Braxton Hicks and it’s feeling like mild/moderate period cramps in my lower belly and back. She’s moving around a ton which is making it all worse and giving me lightening crotch too. This is what I have to look forward to for the next 10 weeks or is this a red flag? I have an appointment in two days. And I’m not dehydrated. I drink 9 bottles a day like clock work
