HI, I HAVE HAD A COUGH FOR ABOUT 6 WEEKS

HI, i HAVE HAD A COUGH FOR ABOUT 6 WEEKS NOW. WENT TO URGENT CARE A WEEK AGAO AND LUNGS WHERE CLEAR VIA XRAY RESULTS. COUGHING UP LIGHT YELLOW MUCUS AND SEEMS TO COLLECT IN THROAT AT NIGHT, CAN HEAR IT BUBBLING WHEN I BREATHE.SLIGHT FEVER NOW AND THEN, NOT EVERYDAY. NOT AFFECTING MY EXERCISE ROUTINE, STILL RUNNING 5 MI EVERY OTHER DAY. NO WHEZZING OR SHORT OF BREATH. MOUTH VERY CHALKY AND LIPS CRACKED. DOES THIS SOUND LIKE ACUTE BRONCITIOS? IF YES HOW LONG CAN IT LAST? THANKS
