Oh the pressure.. literally

Lately, I have experienced this pressure. It’s hard to pinpoint because it feels like baby girl is double fist pumping and she is head down so it’s a sensation in my bum and vag but it almost takes my breathe away. Is that considered Braxton Hicks? I’d say 30% of the time it makes me run to the bathroom for a bowel movement and the other times I just don’t want to move at all and just hope it goes away. Who else is experiencing this? I also have more fluid than normal and because of that have a weekly US. Is there any connection between the two?
