Brown discharge...?

Tarra • I have one son. I had a miscarriage on November 26, 2014. I was 14 weeks and 5 days pregnant, but the baby was only measuring 10 weeks and 5 days.
Af ended on the 3rd, but on the 4th,5th,7th,12th,13th,and 14th I had brown discharge. The 13th, and 14th it was mixed with some red/pinkish blood. Do you think it's anything to be concerned about?
