What's A light bleeding exactly?

I had an unsual light 'period' that came very early close to a week early,  with no cramps along with it. Lasted 5 days but only a day and half of it looked like my period on its last day, rest was just spotting 
​I also had few clots. Is this just one of those abnormal periods or Ib? 
​I had the flu now just have the cough everytime I cough it leads me to vomiting dno :/ pls Help
