To find out what is going on you will need to be thoroughly examined. An examination of your nose and throat will determine the site and cause of the bleeding.
have pink color to my phlem whe coughing up mucus
with antibiotics and zyrtec-d it started to get better no blood in two weeks hope sinus was problem.
If you are forcefully clearing your throat over and over you could have torn it in some way thus producing the blood.
In any event you should call your GP to get some tests done. (Chest and throat CT and/or an endoscope)
