Technically no. A period is when you shed your lining because no pregnancy has occurred. When you miscarry, your body is not only shedding the lining, but also the pregnancy. You will bleed more heavily and it will be more painful. My first period following my miscarriage was very very light. In fact, in only lasted for 2 days. I believe it was because my uterus had completely emptied itself when my pregnancy failed.
