Hey Dan - pretty impressive exercising just a month and 1/2 after Proctocolectomy surgery! Don't hurt yourself - I needed a good 3 months.
I don't have anything to add, Dingbat gave great advice.
I did have a rare blowout during the night last night. I woke up around 3am and felt some wet stuff down there. Too lazy to get up (I know - gross, but it was not a total explosion), dozed until 5:30am and dealt with it. It was change day anyhow. I've been running 3 days a week, and working up quite a sweat, so I suppose this kind of thing is expected.
Plus, I lost track of my last change day, I think it was 4 days, but maybe 5.
