I had a miscarriage on oct 16th 2011 and bleeing for 11 days which was oct 27th, I started bleeding on nov.24th thinking it is my period but it hasn't been enough to soak a pad just light bleeding and spotting some red, some pink, and some brownish red, this has been going on for 9 days now is this my first period after my miscarriage if so how long is this going to last and is it something I should be concerned about?

At this point in time I wouldn't be concerned. Most likely it is your hormones correcting themselves to a pre-pregnant state. Your concern would be if you were soaking a pad an hour. Also, this can fluctuate according to how far along you were in your pregnancy.

I am very sorry for your loss.
