31+4 Bubble feeling in my belly

LC • Sydney - mother of #1 23month old boy and expecting no2 3rd April. Happily married & loving life.

So all night I’ve had a bubble feeling in my belly.... where her feet are and where her back is. I know this as she’s pretty much engaged as I had an ultrasound check. Guess I’m just not sure what it is or why? Should I be worried. She hasn’t really moved the last few hours either.
