Blood in sputum in early morning cough.

Namaste Doctors, I am 26 years old. I had a fever, cough with throat pain last week. I had consulted a medicine specialist locally. I was prescribed crocin 650, indclav 625 twice a day for 5 days, Breaze L OD for 5 days and ascoril d plus cough syrup. I have taken cough syrup much as prescribed. Now, I don't have throat pain or fever but, I have cough and every time, I usually get cough, it takes time to cure. Since, yesterday, I have been seeing blood in my sputum when I get cough in the morning for the first thing after waking up. This persists for 1-2 hours of coughing. Then, the rest of the day, I don't see any blood in cough and mostly, get dry cough. I had a Pantocid dsr this morning. Could you please advise me what I should do ? I usually have chronic tonsil and tonsil stones issues. I am thinking even after taking antibiotics, is the infection still present in the throat or coming from the upper chest. Thanks.
