Whats wrong with me i've been having my period for two weeks?

See Gynecologist: Any menstrual cycle longer than 1 week is abnormal. See your gynecologist for evaluation. Depending on your age, there may be different investigations or interventions. (see my previous answer to another similar question). If you are soaking/bleeding through a pad an hour, you need to go to the er for evaluation.

2 week period: This question requires an examination with your doctor. There are a lot of causes and pregnancy needs to be ruled out.
