Cramps and spotting. Normal?

Brittany
I'm six weeks and one day. I've had moderate cramps for a week now. Started spotting two days ago. It's brown and light right now. It's heavier when I get off work. I'm on my feet all day. I had a miscarriage a few months ago and this is our first baby so I don't know what to expect. The obgyn made my appointment for Dec 4th at 8wks. Should I go sooner?
