Gotta be in there somewhere

I, along with the rest of my class, am dealing with one of the biggest challenges new midwifery students face: finding the cervix. Considering that it is in a relatively small contained area you would think that it would not be that hard to find, but sometimes I can't find that darn thing for the life of me. A couple of times I have found it, only to not know what I was looking at. Not only do they all come in different shapes and sizes to begin with, but they also change as time goes by - especially if they have had a 6-9 lb object squeezed through them.
