Cold water gives me contractions??

I’m 36 weeks pregnant, and it feels like I have constant Braxton Hicks. I was just in the hospital 2 days ago bc I thought I was definitely in labor but they stopped literally as soon as I got to the hospital. But whenever I drink ice water, it gives me contractions!! I can’t drink any other water (not even plain cold water) bc it makes me so nauseous still. I am probably a little dehydrated bc I don’t drink a lot of water but it gives me contractions so I can’t drink a ton at a time! And then I get contractions from being dehydrated 😑 anyone else?
