Internal hemorroids can bleed if they are irritated.
Bad bleeding can look like a bright red jello looking clot attached to your stool also making the water red. (sorry about the gross description
While a small bleed can be a bright red smear on the toilet paper.
They should not give you any pain in your stomach though.
I had 3 big internal ones and I had no pain in my stomach or anywhere around where they were and I did not feel the urge to go the toilet with them.
My hems just bled badly
But they are fixed now
I went to a colon/rectal doctor and he was very good.
Hope my info. helps a bit. take care
