How important this might be depends on information you don't mention. Why are you taking the antibiotic? If for a respiratory infection (e.g. bronchitis), the blood might be due to the infection. If "spit" means saliva, it's more likely from your gums. Discuss with the clinic or doctor who prescribed the antibiotic.
