Explained in detail below.

Detailed Answer:
Hi,
Thanks for the query.I understand your concern.
I had tried to open your reports file..but it could not be seen.
* Probable causes
Blood in phlegm can be some incidental causes like dental injury while brushing, while gargling from gums..mostly blood from mouth is fresh.
Sinus infection can show such symptom
Tocillitis with infection .Both above conditions show blood mixed with infected nasal or sinus mucus membrane..blood with mucus &pus like material is seen.
Bronchitis with secondary infection..blood with thick mucoid sputum mixed with blood is seen.
Deep lung infection with pneumonia.( it can be bacterial,viral infection) mostly it goes with fever,back ache ,cough,breathlessness...here blood is from lungs..so it is deep rust colored,bubbly(mixed with air)&infected material.
But with latest trend of covid..it is seen without fever or cough but back ache & pneumonia persist. Needs to be diagnosed earliest after confirmation.
* Now though you need not be stressed due to the symptom...blood in sputum needs to be attended with a doctor's advise in time.
*Reaching medical care should be
# Immediate-
- coughing up with significant amount of blood,
- Bleed without stopping,
-There is back pain
-feel breathless
#With appointment-
If blood in phlegm is seen first time
Have weakness,loss of appetite
If there is history of smoking.
*In short, Dont neglect.Consultation of a doctor for physical examination &needful investigations followed by specific treatment
Whatever the cause it timely specific medicines & care would resolve the problem.
I hope that helps.Any follow up query is welcome.
Thanks.

Detailed Answer:
HI ,
Thanks for the follow up query.I understand your concern.
In case it was a single occasion of finding the blood tinge to mucus when you spitted first in morning,&never after that..its likely to be due to some injury,cut or bite in oral cavity while brushing,chewing or picking teeth with pin like sharp thing.Please try to point out the cause...start doing warm water gargle for couple of days &forget.Increase vitamin C&B complex supplements (sour fruits&sprouts) in diet.Start brushing with a soft brush.
But if the thing is recurrent,you need to get your oral cavity checked for possible problem to oral cavity ,tongue or gums&get needful treatment.
In case it's associated with smoking,cough or breathlessness...you definitely should get throughly checked to find the cause..get investigated &start with specific treatment.Please don't take it lightly in such a case&consult your physician in time.
I hope that helps.Any follow up query is welcome.Please rate the answer before closing it.
Thanks.
