How is the bleeding today? Is it better or worse? It sounds like it's possible that you may have burst a vessel. Are you having anything else with the bleeding. Like feeling dizzy or faint, normally if you are filling up a pad with blood every hour then you need to go to the ER and be looked at.
If you are just basically spotting then waiting until Tomorrow would be fine for me to do. Now, I'm not a Doctor and can't tell you what to do health wise. You might want to put a post on the Crohns forum and ask them about the rectal bleeding. The folks over there are VERY KNOWLEDGE about stools and stuff in them.
I hope you being to feel better really soon. Please let us know how you are doing, and keep you head up.
