Should I go in?

I had to have a D&C on monday... Dr said most bleeding and pain would be day of surgery and day after... well wed I started cramping horribly and having alot of discharge.. and it smells horribly! The pain is so bad I buckle over. I figured wait it out and see if maybe I just got up too much that day or something... well its now friday and still same thing. She put in for pain meds that I could get but she said I shouldn't need them.... I'm not sure if I should go in and get checked out or if I should just get the pain meds and wait for my 2 week check up next Friday?
