No cold, or anything. I blew my nose, and there was nothing. If you are a smoker, like I am, you know that occasionally you cough out a thick chunk of mucous directly from your lungs. This felt like that, only it was transparent mucous mixed by a fair quantity of fresh red blood. :(
If you're a smoker, or really anyone, this would be a reason to call your DR first thing Monday morning.
