What can it be? Or is this asthma?

Started with a throat infection, i took amoxyclav for 5 days given by ent. On 3rd day, the cough/phlegm from chest came out to be yellowish thick in the morning. Maybe i coughed a lot forcefully, bright red blood came with mucus. I consulted pulmonologist after the antibiotics course, he said acute bronchitis. I was started with bronchitis clear 2x for 3 days. Cough improved, no more thick cough but sometimes after waking up i do get dry cough and after sometimes i need to clear phlegm from chest, little but clear mucus with small bubbles. Apart from that when i palpate on the rib bone it feels tender, both left and right side, but no pain when i breathe in and out deep.. feels inflamed like costocondriotis. What should I do now? I do feel weak after this illness too. Please guide me. Cough has reduced like 70-80%. No fever or anything. Was this something viral? What other medicine do I need to take along with this to recover faster? Or is this asthma?
