I have been coughing up blood since I was diagnosed in 96. I am 25 years old and the blood comes and goes. For the past year and a half I have noticed that I cough up blood around the same time as my period. It has happened the last 3 months consectively and it happened again tonight. My period is due any day. Last month it was the same day that I started. My doctor told me to keep a diary of it so we can look at it over time. Does anyone else have this problem or have noticed it around a specific time of the month or year?
