I am 16 and a half weeks pg with baby number 2 and remember being a little thirsty with DS but this time I am ridiculously thirsty, especially at night, did anyone else experience this?

I'm really struggling of an evening as I get full so quickly from small amounts of food & then am really thirsty & need to keep drinking but end up so bloated I feel sick. I'm only eating small meals (a small cheese & lettuce sandwich for lunch and then a small portion of dinner is all I've eaten today) but I feel like I've eaten a 5 course meal for dinner & am so thirsty it's crazy.

I did a quick google search & gestational diabetes is suggested as a reason for excessive thirst & it also suggests you are more at risk of developing GD if you've had a big baby before (DS was 9p 11oz).

So, after all that! Did anyone have excessive thirst, especially at night? If so, was it a normal pg? I'm not sure whether I should be concerned about GD at this stage?
