If the egg is not fertilized, hormones stimulate your uterus to shed the lining at the end of your cycle. This shedding is your period. Experiencing a heavy or even a normal period means that you cannot be pregnant, since your uterus has shed its lining instead of maintaining it to sustain a fertilized egg.
Heavy or prolonged menstrual periods, or menorrhagia, are the most common type of abnormal bleeding from the uterus. Periods are considered heavy if there is enough blood to soak a pad or tampon every hour for several consecutive hours. Other symptoms of a heavy period can include: Nighttime bleeding that requires getting up to change pads or tampons. Passing large blood clots during menstruation.
