Two Sigmoidoscopies, Colonoscopy next?

Don't be scared Megan - they are only trying to find the source of the bleeding and generally, as you mention, brighter blood usually indicates a source lower down.

I had a colonoscopy last week and it wasn't as painful as many describe - I opted for painkiller (Fentanyl) and bowel relaxant (Boscopan). It was done by a nhs consultant who had done many within his professional practice (They recommend at least 300 a year for colonoscopists to keep their skills up!)

tbh - I'd much rather have the colonoscopy to rule out or deal with anything as soon as possible. They can even detect crohns desease which may be responsible for similar symptoms.

I too had blood in stools, though I would describe it as dark, plus anaemia and was really worried about colon cancer; but they found no polyps and no suspician of cancer, but it was really reassuring to rule that out at least. Plus, if they had found polyps that can turn into cancer, the colonoscopist could have removed them - so anyway you look at it - the procedure makes sense.

As a rule the fresher and brighter the read then the nearer the end of the colon it is for obvious reasons but I expect there are exceptions to that. Fissure and piles generally show on the paper so the way you describe does suggest to me a small bleed somewhere. Best to get it checked out. Everyone always fears the obvious but bleeding can have lots of causes. Whatever it is, best to find it while it is still producing mild symptoms. Oddly, I find a colonoscopy less uncomfortable than the sigmoidoscopy. I don't think there is any need to get unduly worried (I know we all say that and never follow our own advice) but you would be devastated if something developed and you had decided to risk it when it could have been sorted now.
