I have felt this occassionally so far. It is horrible! I wonder if the baby has decided my bladder makes the perfect cushion and just plants his little booty right on top of it.
I guess our bodies can't really tell the difference between the pressure of the baby and a FULL bladder????? All I know is that there are moments my body is SCREAMING at me to GO! GO! GO! I rush to the bathroom and there is just....nothing.
