Also this is my first baby so idk if I'm just paranoid?
If something is wrong, you would feel worse because you didn't get checked out. I doubt there is problems with blood circulation, but talk to your doctor about your concerns. That's what they're there for. Even if you're not thirsty, you need to drink a decent amount of water. They will be able to check your fluid levels on an ultrasound if they choose to do so.
