See your dr.: Any menses lasting more than one week need to be investigated. Need pregnancy test. You need to see your doctor.

Not normal: Bleeding for more than 7 days is not normal. It can have many causes--from pregnancy to stds to other infections to fibroids to endometriosis to other causes. Keep track of your periods on a calendar and discuss with your doctor.
