Decreased urine?

Kinsey
I'm 38 weeks, I have been drinking a lot over the weekend because I've felt extra thirsty. I woke up several times last night because my toddler is sick, I usually pee slot through the night but last night I barely had a trickle each time. Throughout the morning I've barely had any urine come out still.. And I don't feel like I need to go which is very unusual at 38 weeks! I have felt a bit of nausea but not too bad and no other symptoms. Has anyone had the same experience ? Should I wait it out or call?
