Old Blood: This is more common when changing hormonal contraception or from endometrium that didn't shed with the previous cycle. Old endometrium or old blood is darker, often stickier & is not a problem unless it persists. After 3 similar menstrual cycles with dark black blood, see your gyn for an eval. Take care.
