Maddy I had almost identical issue a month ago. Now i take metamucil which I should have done in the first place but the ibd nurse put me on a laxative called lactulose. I was on the laxatives for a week and blood came back. I did a quick taper but started at 25 mg and blood went in 3-4 days. So as i was always told not to change anything till blood has gone for 3 days.
I did 25 1 week then 15 1 week then 10 1 week then I am now doing 10 day 1, 5 day, 2 10 day 3 for a week (so 7.5), next week 5mg. then I will start 1mg pills starting at 4mg a week and so on till 1. my last week i will do 0.5 by having 1 then nothing etc.
My advice to you as I have also been on pred on and off for 1,5 years and was also 2 months off when this happened is;
1. dont move down too quickly if blood is still there wait till its gone, then move down quick to 30
2. from 25 follow what i did cos i have seen no blood
2. DO NOT IGNORE CONSTIPATION WHILE YOU DO THIS. By that i mean introduce the right fibre in to your diet slowly. I have introduced 1 x capsule of metamucil with each meal and now i am going to move up to 2 capsule in the evening meal. I also drink half a cup of prune juice in the evening to soften things if I get pains. This has meant i am regular 1 or 2 bms a day formed and no problems tapering otherwise constipation will cause issues again. I think the pred it self has something to do with this because the bowel does not heal properly on it and forgets to work in a normal way especially as we have both been on pred too long.
Good luck i hope this helps
