I Need Some Advice . Please help

Kris
So I'm 23 weeks today and I'm having trouble staying hydrated. I've been diagnosed with low fluid . I upped my water intake to 100+ ounces a day.. but I'm still chronically dehydrated. I'm always thirsty and my pee is always dark no matter if I drink water.. gatorade.. juice.. flavored water... it doesn't matter. I have been tested for GD and don't have it. Any tips ladies? Should I opt for iv fluids. I don't know what to do anymote.
