Breakthrough bleedin: It sounds like breakthrough bleeding, when the lining becomes unstable and breaks down a little, causing bleeding. The dark blood suggests old blood. Don't stop your pills, because this does not effect the contraceptive aspect of the pill. The change in your physical activity may play s role. If it keeps happening, you may need to change your pill.
