Since I've been pregnant I've noticed that my urine is always a dark yellow, and I've been waking up early in the mornings with a dry mouth. I have been drinking a lot more than usual, and normally this would leave me with quite clear urine. Do I need to start drinking even more? I usually have a glass of fruit juice in the mornings, followed by copious amounts of decaff tea during the day, with a 500ml water bottle on the go at my desk as well. Too much tea perhaps?
