As the fertilized egg traveled down the fallopian tube this past week, it underwent lots of changes, dividing into a mass of cells, each one with a special purpose. Some will eventually be our baby's organs. All of our baby's characteristics are already determined - sex, hair color, eye color, blood type, etc. I wonder who he/she will look like? The time is approaching for my period to come again, and I'm trying not to think about it too much.
