This morning i woke up spitting bloody mucus and later on today i had a bloody nose what should i do? i smoke.

You : You need to be evaluated by an otolaryngologist in short order. Although bloody mucous can be benign secondary to bloody nose dripping into your throat ordue to local irritation/trauma in the throat from dry mucosa, coughing, gagging, or throat clearing, your history of smoking warrants a thorough evaluation of the nose, mouth, pharynx, and larynx (and possibly the lungs) to rule out more serious causes of bloody mucous. If the blood is determined to be from the nose (epistaxis) your physician will counsel you on treatments to decrease the risk of continued bleeding, and may even treat you in the office. If there are other reasons for your bleeding additional testing and/or therapies may be needed, but it is imperative to have a qualified ENT examine you.

See your doctor: Having blood in sputum (phlegm) is always worrisome, although much less so at your age, and may be related to the bloody nose. Smoking cessation would be my first thought, since it is likely a bronchitis, which is either caused by or worsened by smoking. Please talk to your doctor and strongly consider smoking cessation.
