I have had a stuffy nose with yellow snot, sore throat with no cough, and a little bit of blood in my mucus this morning. This all started 8 days ago?

Likely sinusitis. See your doctor for vasoconstrictors and possibly antibiotics. Make note of your blood pressure and if you are on any blood pressure medicines as these can contraindicate some drugs. Also, drink plenty of fluids and consider nasal sprays and mouth washes.
