Hi there, i have been VERY thirsty most of my pregnancy. Sometimes i can't drink enough. It comes and goes and was worst in the second tri. (Pre preg i could go a whole day without a glass of water and 2nd tri i was drinking upto 3L a day, have curbed the water at the mo b/c i need to wee every hour or so! LOL)
Excess thirst can be a symptom of diabetes, but the general concensus with my preggo friends was that you get very thirsty when preg. I have also heard it gets worse when breastfeeding, SUPER THIRSTY!
