It's normal for thirst to increase during pregnancy due to the extra blood volume etc but just to be on the safe side perhaps have a word with the midwife about getting checked for gestational diabetes. It's probably not that but better to be safe xx
Im the same way. I wake up in the middle of the night very dehydrated and then i drink so much, Im either waking up to get something to drink or to go pee pee. I drink water and gatorade all day at work and still feel ;ike I just ran a marathon and havent drank anything at all.
