I noticed some blood clots on the toilet tissue. The GP checked for haemorrhoids but found none so asked for blood and faecal tests. They came back normal. We thought it was Irritable Bowel Syndrome and I began to change my diet to see if that would help. At the same time, she asked me to have a colonoscopy, just to be on the safe side, saying we had to find out what's going on. She didn't pressure me to have it, but my husband did. I procrastinated for a week debating whether this was really necessary.
