After ds was born (9lbs) I suffered, and still do, from retained urine in that I often get the urge and then have to sit for ages before anything comes out. I am now pg again (ds is 19 months) and I have been told by the midwife that I need to get it seen to. How serious is this? Is the 'seeing to' unpleasant and what does it consist of? Any advice... please...
