Talk with your doc. Ff your period lasts longer than 2 weeks, then talk with your family doc or gyn. Other warning signs: bleeding so heavy it soaks at least one pad or tampon an hour for more than a few hours, irregular vaginal bleeding, any vaginal bleeding after menopause, feeling lightheaded or dizzy. Great question. Hope you feel better.
Need to see doctor. You need to see your ob/gyn doctor. A period longer than a week is abnormal. You need evaluation and a physical exam.
