Pregnancy a Week by Week Guide

• Pregnancy week by week at week six. The babies first heart beats have begun! The baby is now an embryo and is about 1/17 inches long. Growth will be very rapid this week. The umbilical cord will develop at this time. The eyes and ears begin to form as well as an opening for the mouth. The heart has begun to pump blood and most of the other organs are well under construction. Buds form on the body that will become the arms and legs. I think this is a very exciting week.
