Is this TB or just bronchitis? Tb?

I have been having cough since 20-25 days, cough has reduced since last 7-8 days however phelgm is still there.. No classical symptoms of tb like fever, night sweats , weight loss, even cough is less. Symptoms: Clear to whitish bubbly phlegm while coughing, had two episode of hemoptysis due to forceful clearing of throat. Post nasal drip has thick white mucus sometimes. Can you please see this xray and guide me? Is there any markings or signs suggesting tb? The pulmonologist has asked me to check for cb naat for being on a safer side.. First pic is latest chest xray, 2nd pic is xray taken 3 years back, also please guide me if there's any difference. That tkme also i had a bout of cough. Thank you doctors.
