For weeks i have had extreme dehydration and it has now got to the point where i'm waking in the middle of the night desperate for a drink. mouth feels dry all through the day despite having plenty of fluids. Went to my booking in appointment yesterday and midwife seemed concerned about it. She mentioned that it sounds like diabetes. Diabetes runs in my family and my mum also had gestational diabetes when pregnant so there's a high chance i could get this. Has anyone else had dehydration during pregnancy that is becoming unbearable that hasn't turned out to be diabetes?
