I am an allergic bronchitis patient and currently 15 weeks pregnant. I have been experiencing a viral infection for the past 10 days, with symptoms including fever, cough, and cold during the initial 3 days. Due to my pregnancy, I have been cautious about taking medications, but I did take azithromycin 500mg for 3 days, along with cetirizine and montelukast. While my cough has improved, I have noticed the presence of blood in my phlegm only in the morning for the past 3 days, and it seems to be increasing. I am seeking advice on this matter. Thank you.
