In so much pain!?

Is it normal to be in really sharp pains in my uterus up to 2 min long and bleeding alot? Its been over a week since my baby has been gone ans i habe a dnc scheduled foe 9:3p am Tomarrow morning. Should i be concerned. About the pain? Nothing really has been helping tramadol, ibuprofen, advell , nore a heating pad....what should i do?
