excessive thirst 4 weeks pregnant

Alex • Blessed to be mom to our miracle IUGR baby boy! I've never met someone as strong and brave as he is!
Is excessive thirst a thing or should I be concerned? I've never drank this much water and I still feel thirsty! I'm only 4w4d pregnant and I don't have a history of gd. This is my first so I'm nervous it could be bad? Or is it just a normal symptom like everything else? Of course I'm going to ask my dr but I was wondering if you all had this?
