Looks like one of the poisonous plants: http://www.flickr.com/photos/76284694@N02/9245523300/ Growing wild in Michigan forests, flowers are pink (even though they appear to be white in this picture because of the light)
Here is a picture I drew with Microsoft Paint that shows generally what the plant looks like: I know what the leaves look like and I know the flowers are pink, but I don't know exactly the shape of them, but as far as I can remember, those are what the flowers may look like. http://www.flickr.com/photos/76284694@N02/9244941343/
Not poisonous. One of the desmodiums. (Desmodium glutinosum) http://wisplants.uwsp.edu/scripts/detail.asp?SpCode=DESGLU http://www.discoverlife.org/mp/20q?search=Desmodium+glutinosum I answered your post at YA, as well.
