Brown Discharge Normal or Abnormal??

I am approximately 6-7 weeks pregnant. For the past 3 days I've had this weird brown discharge when wiping. A dark brown. Kind of like old blood and white mucous. Yeah it sounds gross. I've looked online and I can't get a clear answer if it's normal or not. I go to the doctor in a couple of days but I just wanted to ask here to get some answers.
