So thirsty and tired!

Jessie • Mum of 1, another baby due in may 2020

I’m 11 weeks 5 days and for the last few days I have just been so tired and thirsty! Waking up in the night just because I need to drink. It’s quite hot in the uk and the moment and me bedroom is sitting at 28 degrees c with a fan on. I’m drinking water all day but just feel almost like I’m hungover. Anyone else experiencing this or am I just weird?
