The reason that you are coughing out blood when you cough hard is because when you cough hard, you damge the veins in your lungs which release blood, and as the blood needs to gos somewhere it goes out your mouth when you cough. I suggest not coughing so hard if you can or taking antibiotics or peniccilin to help relieve your cold.
