Firstly I've got a call back from the GP sometime today to discuss.

Sometimes, for whatever reason (possibly due to pile flare-ups or stress/diet) I get flat, ribbon stools and then it goes, but over the last week they have persisted. I increased the quality of fiber foods which which appears to make them look more normal or normal bulk size but flat on one side or just oval shaped. 

I had a FIT test in April and October last year 6 which was ok. Now I just wanted to share this with someone and speak to the doc about it.
