Sounds like it could be your period. Light periods can be brownish/blackish. This may be what is normal for you, or it may become a bit heavier over time. Next time you notice the discharge, if you want to know where it is coming from, put you finger (make sure it is clean) into your vagina and see if there is any discharge on it when you remove it
