an odd symptom perhaps but for the last week or so i have been REALLY thirsty - no matter how much i drink it just doesnt seem to go away. i have been trying over the last couple of days to make sure i drink about 2.5l of water but i am still thirsty, especially when i wake up. i am a bit worried as my mum is diabetic and i know that they want to test me for gestational diabetes at 28wks. should i be worried? has anyone had this and its gone away?
