Spitting up blood

just wondering if anyone has had this experience, I really need reassurance. I am worried sick. I had a really bad flu. the cough lasted 3 weeks and it was quite severe. Yesterday morning a few minutes after brushing my teeth I gagged and spat in the sink only to see there was pink blood mixed in my sputum. my mind has been spiraling since. it hasn't happened again but scared it will.

Hi Cindy, you need to see your doctor to be on the safe side, especially when you stated the bad cough lasted three weeks…Good luck
