Left breast bleeding only 32

Hi, ladies I went and saw my doctor Thursday he said I need to be referred to breast clinic, because all of a sudden I have bleeding come from my left breast along with milk traces. I haven't breast fed my 4th child for over 2 years! She is 3. 
Im off to breast clinic this afternoon, was just posting to see if any one has had this before?

 

please hit my mind at rest 

 

thank you
