This depends upon whether a D&C has been performed or if your miscarriage is being passed naturally. Passing a failed pregnancy naturally, bleeding may last for one or two weeks. It should be somewhat heavier than a normal period. With a D&C, the period of bleeding is shorter and most bleeding or spotting will stop within a week of the procedure. However, if large clots begin to pass or there is bleeding over one large pad per hour, you should be evaluated by a medical professional. In addition, if there are symptoms from the blood loss such as lightheadedness, dizziness, severe fatigue or chest pain then you should also seek medical care immediately. After the initial heavier blood loss, spotting and brownish discharge may continue for a week or two.
