Spotting/bleeding

How long did you spot/bleed before you eventually miscarried?

I'm 6w3d. I've had brown discharge off and on since last week. Since Sunday it's been more frequent (ie every time I wipe). Yesterday it turned pink and then reddish mucus. There is a smear of brown on my panty liner. I'm continuing to wipe red/pink/brown. I called my doctor and they moved my first scan up from Tuesday to tomorrow.

I have a bad feeling about it. This is my 5th pregnancy, and I've never experienced this. My previous miscarriage was missed and had a d&c, so I never bled.

If it is a miscarriage, I'm just ready to get it over with.
