Light brown discharge?

Ashley
Has anyone else experienced light brown discharge? I am 6w4d and two days now I have had light brown discharge. It is not constant, only happened once yesterday and once today and not very much. I called the Dr and they told me not to worry unless it was bright red. It still scares me though. This is my first pregnancy so I'm not sure what is normal.  I also have been experiencing very light cramps since I found out I was pregnant.  Anyone else in my same boat?
