I’m 29 weeks tomorrow and have barely drunk more than about 20 glasses of water for the whole of my pregnancy and now I’m a bit worried. Water, bizarrely, gives me headaches and so I just can’t drink it. I have decaf tea throughout the day, probably 6-7 cups, take my pregnancy vitamins with 150ml of orange juice and then that’s kind of it. I just don’t get thirsty. Am I doing damage to the baby?
