My Stomach Has Grown In The Past Month. I Look

My stomach has grown in the past month. I look like I am 5 months pregnant. At dialysis my Dr said my bladder felt full. I still pee but not a lot> I feel like I have to urinate all the time. Every time I eat, which isn't much, I have a bowl movement. they tried inserting a tube into my bladder to see how much urine they could release, the tube only went in a little ways and it was blocked from going further. Was sent for x-ray. now I'm waiting and I'm worried.
