It just usually means that some of your remaining blood from your last period is just being washed down thru your normal secretions. That is why the discharge is brown. If the discharge is brown, that is not a sign of fresh bleeding. Fresh bleeding would be bright red. I think that you're ovulating and your normal secretions is cleansing out the last of your period. If it keeps up and doesn't stop over the next few days, then I would get myself checked out. Think of when you have had a nosebleed, sometimes the lining of your nose has dried blood in it, then when you sneeze and you blow your nose the tissue has brown mucus on it. Could be the same thing happening down below.
