There is actually a name for this type of condition. It is called Menorrhagia. There can be fluctuations in the amount of bleeding from one woman to the next, but for some women the bleeding and cramping would be enough to cause an interruption in their lives each month. If you do, in fact, have Menorrhagia, then there are a number of different causes as well as different treatments depending on the cause. You will need to speak to your doctor about your concerns in order to reach a diagnosis.
