Feeling like a fish out of water!

I have had excessive thirst these last couple of weeks like no matter how much I drink my thirst isn't satisfied! I drink tons of water so I'm constantly urinating. It's not gestational diabetes they've checked twice because my diabetes runs heavily in my family on both sides. What can I do to calm this thirst lol probably nothing but I wanted to see if any mamas were experiencing this symptom late in the game like me!
