Tuesday, the day of the ultrasound, was the start of week 7 - or day 49. They are barely the size of a grain of rice right now. I-Am-Pregnant.com tells us the following:
This week your baby has an amazing growth spurt. At the beginning of this week, your baby is approximately 4 to 5 mm and by the end of the week it has more than doubled to 11 to 13 mm! Your baby weights approximately 0.03 ounces. Your baby's leg and arm buds are longer now and they have divided into segments where the hands and feet will be. The hands and feet also have an area where the fingers and toes will begin to form. At this point of your pregnancy, the heart is bulging from the body and it has divided into right and left chambers. The brain's hemispheres are continuing to grow and the air passages into the lungs are visible. Your baby's eyes are beginning to get pigment. The nose is developing and the beginning of the face can be seen. The baby's abdomen is developing quickly and the appendix and pancreas are already present. Your baby's digestive tract is beginning to form and the hindgut is present. The shape of the talk can still be seen, but it will fade in 3 or 4 weeks.
