I had the most horrendous dry mouth and felt dehydrated all of second and third tri and also measured big but tested negative for GD - didn’t have anything in my urine though but you never know!
I'm 20 weeks and they haven't commented on percentile. I've been told I'm at risk of gd. Also very dry mouth when I wake up. I go back on 9th for appt and glocose test so will find out then. Fingers crossed none of us end up with it 🤞 who knows though ah.
I had this with the same belly measurements at 20 weeks scan but GD was still normal and they have slowed down and now around 50th percentile :)
