I've had some blood streaked sputum in the past. How seriously you need to consider it depends on what the color of the rest of the sputum is. In a majority of cases, blood streaking indicates some form of infection. Other times it may just be that you coughed a little harder than your lungs could handle. Do mention it to the doctor, but you don't need to lose any sleep over it. Make sure you're taking your vitamins, especially vitamin K which helps keep bleeding issues under control.
