Why is there continuous bleeding after menstruation?

there shouldn't be continuous bleeding after menstruation if you find that your period hasent stopped after the seventh day you are probubly just having a long period they can be as long as 9 days or a short as 3. if you are taking birth control that can also make you have continuous bleeding for a long time .. EITHER WAY YOU SHOULD DEFINATELY GO SEE A DOCTOR... if the bleeding does not stop. ~good Luck~
