Any Advice or Reassurance?

I'm 6w 1d and I had a on and off light brown spotting since yesterday evening, but it's not turning into a bit of a pinky brown colour. It's only when I wipe so it's not heavy, but I've already had one early miscarriage I don't think I can cope with another one. I have the same sort or ache I've had since I found out so I'm not having cramps or anything. I'm booked in to see my doctor Friday for my first appointment. Anyone had similar?
