just to let you know about
my experience.... might ease your mind a little...
but for a year now, i bled every time i went to the toilet which was up to 20+ times a day.
there was lots of blood everytime.
even if there was no poo, there was still blood.
i became aenemic like a bunch of times and had to have iron infusions due to the bleeding.
definitely see your doctor about it, but its not uncommon to bleed a lot with UC.
