My bladder has felt really bruised and massively full all day ( a bit like when you wake up from a long sleep needing the loo) Only difference is I've been to the loo about 6 times in the last half hour and nothing much comes out. Just feels like i'm desperate to go to the toilet all the time. I'm 28 wks pg, do you think its just the baby pressing on my bladder or should I get this checked?
