Oh CM
Please don't worry. Brown blood really isn't much to worry about, especially in such a small amount. When it is bright red, clotting, with pains, then it is time to worry.

Even with that said, with my DD I had bright red bleeding at 16 weeks (she is now a happy, healthy 3 year old)
And I also had bright red bleeding with DS at 6, 7, 11, and 15 weeks (and he is now a happy healthy 1 year old)

lots of sticky vibes coming your way!
