I Am Going In For A D&C On Monday. I

I am going in for a D&C on Monday. I have been taking Black Cohosh and Prolamine Iodine to help with hot flashes. I took both of these yesterday. Now I see that I should have stopped all supplements a week or two before surgery. I won't take anymore, so it will be at least 48 hours before surgery since I've taken these supplements. Do I have anything to be worried about?
