How To Terminate Unwanted Pregnancy?

Hi, I was given the option by my doctor to do natural miscarriage or D&C . I want to know some methods I can use to speed up process for a natural miscarriage. For example I have heard the ground cinnamon can reduce the pain and speed the process along. Also how much should I intake without causes any more harm to my body. By the way I just found out my baby died at 8 weeks and don t want to have to undergo anymore medical procedures. Please respond as soon as possible.
