Hi, I have not't been on this board before but the same thing happened me yesterday and I'm trying to find out more about it. I am 12 weeks pregnant and had a scan yesterday where the babys bladder is too big. My consultant felt it could be distended but wanted to get a 2nd opinion on it. She is supposed to be ringing me today to go back to meet a radiographer and be scanned again and see what his opinion is. I have looked up information on distended bladder on the internet (that is how I came across your post) but it seems very hard to get any real information. I wish you luck and hope that someone with more experience can reply to you as I would also be very interested to find out from someone who knows about it.
