Just had the stomach flu (I know, not a "flu" but a gastrointestinal virus :) )... anyways, after first session of throwing up my nose was FULL of blood, fresh blood. Blew nose with three or four Kleenex; every time the Kleenex was full of blood. This happened the following couple of times as well, although not as bad. Also I continued to cough up blood, but this was more blood and mucous mixture. At some point, it lessened and changed colour, darker. From the first time on my throat felt quite swollen, still does to a lesser degree, and I really was choking a few times when throwing up.

Should I be concerned? Is it possible that something else is going on, besides the stomach bug, that I should be getting looked at?
