Get it checked out immediately I would think. I would also call your Dr. and see what they recommend - make sure you talk with your dr or a nurse that will speak to your dr. or another dr ASAP.
Just my 2 cents, I would not wait - any form of bleeding that comes that way needs to be investigated right away.
