It started really light, more spotting really and has gradually got worse.  It doesn't seem as bad as a period (mine are quite heavy) but there are quite a lot of clots and some seem big and I have had the occasional gush .  I don't have any signs of anemia, but all this blood loss must take its toll.  
I am worried that it is something other than a long period, even my doctor said I was a little young to be starting the menopause (I'm 47), but I know, after reading this site that I am not young at all.
