I have had bad 'IBS' for years. Around the end of August, I noticed a  lot of blood in my stools, constant diarrhea and crippling fatgiue. Had an examination and nothing was found, so was asked to do blood tests, which all came back clear within 3 days, a FIT Test and Calprotectin. It's now been over 2 weeks and the GP receptionist told me, these tests can take a long time and I should ring back after 3 weeks. Has anyone else experienced this? I was unfortunately, under the impression, results take two weeks.

Not sure, if I should take the no news, is good news approach or if it's taking longer for a worrying reason.
