I have ulcerative colitis, not crohn's, so I'm used to bleeding... There's blood every time I use the restroom. I know it's more common to have bleeding with UC so I don't know if it means anything differently if you have it with crohn's. It could possibly be internal hemmorhoids though or maybe a fissure.. Was it bright red blood? A lot, or a little? Sometimes I have blood just dripping out and turning the water red, other times it's just on the TP. It is pretty scary though!
I would call your GP and see if they can get you in sooner with the GI (yeah, I know how that goes, it's so stupid!) but otherwise the best thing to do is just keep an eye on it and remember that when blood mixes with water, it looks a LOT worse than it really is- sometimes it looks like I lost a pint when it's probably just a tablespoon! lol
Good luck and try to stay calm (I know, I know, easier said than done)
