Kill me.

Weeks ago (5-7 weeks ago) I started my period. It lasted 5 minutes aprox. I thought it was being my normal irregular period. It came on and off all that week which seemed normal because my periods are irregular. But never has my period lasted 5-6 weeks, I am still on, and I am scared. I do not know what's going on. Any thoughts before I go to the doctor? (So I don't look like an idiot)
