Suggest Treatment For Throat Infection

I was brushing my teeth and when i finish i clear my throat to clean out any mucous from throat from brushing teeth and tho the mucous was clear fluid/spit there was a rife of blood...i wanted to be sure to wasnt my gyms/teeth as i have had in recent times but when i rinsed without coughing there was no tinge of red but when i forced to clear throat again there was the red timge of blood again...i never had this unless i had a throat infection of some sort with yellow mucous with a tinge of red if that...but this is clear spit with the streaks of blood...I am freaked out and scared...could it be just an irritation of throat strain from yelling as i did last nite and felt my throat hoarse afterwards...or from an irritant such as a pesticide i sprayed 2 days ago but wore a paper face mask - but tho i wasn t sure afterwards if i could totally trust the mask and of course was provably breathing out of my mouth i gargles a few times afterwards just in case...and now that i seen the blood tinge in hindsight i am recalling my last stool early this evening was initially on the dark side and then light and softer when ending..could this just be something Minor irritation...or my worst fear cancer
