Blood from the drain could mean a couple of different things, none of which are too "bad" in my experience ... a bump the wrong way, a bad position in my sleep, and long car rides were usually the culprits of bleeding. Once it was just that the abscess was healing and becoming more shallow, so the doc had to cut a couple stitches to loosen the drain and all was well.
It's good that you're going to see the surgeon today so he can take a look and make sure all is well, but I wouldn't chew your fingernails off in the mean time.
And, I hate to sound like a broken record, but this is advice for anyone that has a drain...
Have your surgeon DRAW the specific type of drain that you have it so that you understand it (and ask questions on here if you need to). Have your surgeon explain exactly how it is supposed to heal, and what modifications may be required in the mean time.
Surgeons especially are not known for their "people" skills, so corner him while you've got him and make sure he doesn't run away until you're satisfied.
I hope you and your daughter get everything straightened out this afternoon!
