I'm 6 weeks!

Your baby is about 1/2 of an inch in length (from crown to rump) and is experiencing rapid growth. Limb buds begin to appear on the body, which will later form your baby's arms and legs. Mid-way through this week, your baby's eyes begin to form and tiny depressions will start to appear on either side of his or her head where the ears and inner ear will later form. Your baby's digestive system is becoming more refined as the stomach and intestines develop. The appendix is in place now, as well. At this point, your baby is completely enclosed in the amniotic sac and the stalk begins to grow into the umbilical cord, forming blood vessels within. Your baby's heart is beating and pumping blood, providing circulation for its tiny body this week.
