I'm 19 weeks pg with dc2. I'm horrendously thirsty all the time, and completely knackered. I'm also at risk for diabetes as my dad has it, (type 2)plus am overweight. On the other hand, I've just got over a reallt bad ear infection/throat virus type thing, which could be causing the dry throat and the tiredness. I don't know! Feel like I've been at the docs every week for the past three weeks, so don't want to go again if I'm just taking a while to recuperate. Any advice welcome...
