As long as your over 37weeks. This is fine. It sounds like the early stages of labor, what the "gooey brown stuff" was your mucus plug! For some, this doesn't mean much, sometimes people loose their plug and don't deliver for a month! But since your having contractions, I'd say early labor, as the other poster suggested, sit down, relax for a bit, try drinking water, if the pains don't go away after changing your activity, then its not BH. Its real labor.
