I have been on my period for 10 days I am usually a 5 day period what could be wrong?

This will sometimes happen if you are under some kind of undue stress,or if your body has not completely "cleansed" itself,so it will take some time.During this time make sure you drink plenty of fluids,and take some iron supplements if it leaves you feeling fatigued.If it lasts any longer than 14 days,you should see your physician,as you may have some internal problems.(You need to "relax"....if you are uptight about something.....take some "me"time for yourself...I have a feeling you are worried over something....)
