Usually it is just mixed in the my saliva in small specks, but on one occasion i tasted blood
in my mouth and had to spit
it out into a tissue. It wasn't an alarming amount, just maybe a little under a teaspoon.
I've had a serious phlegm issue going for a while too, constantly having to clear my throat, with lots of bubbly, thick white ( or perhaps pink, hard to tell ) mucus. This sometimes makes me feel a little sick, but I've never vomited any up as yet.
