Wait it out: and if the blood persists after 4-5 days, consult you primary doctor. A chest xray and blood tests will probably be ordered. You did mention any nosebleeds or gum bleeds or tobacco use so I presume they're not a problem. But coughing blood-tinged sputum during acute bronchtis is relatively common.
