I have tried to check for an update but mustn't have saved the thread. It was in November or December and the OP was losing shocking amounts of blood. But she didn't want to be bleeding in A&E so would go to the toilets and subsequently staff at the hospital were giving her the brush off. I think someone said to her "do you expect gastro enterologists to work at the weekend?"
Other posters were advising her to mention/query Crohn's / ulcerative colitis
I hope she's ok
