Watch carefully: This is unusual. Check and watch for the source over the next 1-2 weeks. It is likely to settle down itself.

Blood in mouth: Most common reason is inflammatory infection called gum disease or periodontal disease. See your Dentist for periodontal screening and, if indicated, treatment or referral to Periodontist (gum/bone specialist).
