Nailit, I had the same problem,loads of blood, terrible urgency, sometimes not even making it.
My Doc kept saying bit of blood =piles and sendig me away.
It wasn't a bit , was a lot.
I ended up covering an old tray with tissue and 'going' on that and taking photos. Showed them to my Doc and was seen in Gastro in a couple of weeks.
Turned out I had Crohns, this was nearly 30 years ago. I'm pretty stable on meds now, few flare ups ,but nothing major.
Go and see your Doc, keep going, til you get seen and checked out.
All the best, Sparkles. X
