Blood/mucus stool

Hi

For tge past 8 months ive had blood and mucus in stools, i went to the docs and they said IBS, tge symptoms persisted so i went back, they took blood tests which were all normal, a stool test which said i had high calproctin levels (1200) so gp said i had suspected IBD, i have a colonoscopy appt in 2 weeks. Obviously no one can diagnose other than the docs after colonoscopy but im freaking out and expecting the worst! Has anyone else had anything similar? I have absolutely so other symptoms just mucus at rhe top of stool (first bit to come out) then blood on the outside sometimes quite a bit sometimes barely any and thats it but it has been every stool apart from maybe 5 in total for the last 8 months! Maybe a slight niggle in left lower side of stomach occasionally right but nothing major at all.

No family history, no weight loss, no tiredness, bowel habbits normal, no pain, no other symptoms, just an increase in anxiety!

Thanks for reading
