They are pretty normal symptoms , I wouldn't bother too much about the mucous and blood for the initial month. After that it will just be mucous/ yellow residual stool. J pouch is partially connected to the intestine so whatever you'll eat some fluid will pass through causing you to go and its the glands which were around the colon which used to produce mucous that still keep producing it that causes mucous formation post op. Also you need to remember that entire colon has been pulled out of you by cutting it so pain on the insides is normal too. It will all decrease with time and once jpouch is connected and it stablizes the mucous and other issues will go away too.

For the mucous part I too used to fret alot with it but after a month, one day I held back for as long as I could and it reduced drastically. The more you go to release it , the more it keeps on building. That was how it went for me.

Hi stitched together,

It is a long road, but it does get better! The mucous and blood to defacate  is normal and the urgency should improve over time. If not Id ask your surgeon to make sure there is no residual UC in the cuff (did you have your surgery for Colitis?)

Are you connected at all? For my stage 2 my pouch/anus were completely separate from the small bowel--you are "disconnected" to let it heal, so nothing should pass through (but this was 20 years ago so maybe things have changed.....). Taking 12 hours for food togo through sounds suspicious though, is it like nothing for 12 hours and then it comes? Your bowels may be "waking up" but it is a long time. I think within c. 1-2 weeks of surgery my stoma produced things pretty regularly--maybe every 2-4 hours or so.
