Hemroids+bleeding. Advice Please

Hi, after having hemroids last year I was not overly worried when I developed one 5 days ago. I bought some cream and in the past few days the size of the lump has shrunk and the pain is less. I had been drinking lots of water and fruit juices to allow for easy stools, although I have been refraining form going to much. Tonight when going to the toilet I past a lot more blood than I would think normal for hemroids. Although I had noticed some bleeding when applying cream, I wasnt very worried, but when at the toilet the water had turned red and there was loose fluid blood in the basin. I hope that its just the rupture but I am rather worried. Its not bleeding now however, definatly not in the way it was before.
I would realy like some advice. Just how much blood can there be? Should I go to the doctor?

((didnt realy know what section to post this as there was no hemroids section.))

thanks.
