This week and next, according to Storknet

I thought this was interesting and exciting. Keep in mind, I'm 6 weeks, 5 days today.

Week 6
Fetal Development:
My Heart Belongs to You!
The first heartbeats have begun! The baby is now an embryo and is about 1/17 of an inch long. Growth is very rapid this week. The umbilical cord develops. 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.
Exciting week!

Maternal Changes:
This week tends to bring on the nausea. Morning sickness is a constant companion any time of the day. You may be craving certain foods while the very thought of other foods will send you to the porcelain goddess.
Because this is a critical time in your baby's organ development, avoid alcohol, substances, drugs, and treatments (perms, hair coloring, manicures, etc.) that you don't really need. If you haven't yet, make your first prenatal appointment with your care provider.

Week 7
Fetal Development:
I'm Tiny But Gaining Fast!
The baby is about 1/3 of an inch, the size of a grain of rice. Development of the arms and legs continue although the fingers and toes haven't yet formed. The brain is growing as well as the lenses of the eyes, nostrils, intestines, pancreas and bronchi.

Maternal Changes:
This week tends to be like last week with the usual symptoms of early pregnancy continuing. You're not showing yet and may have lost a few pounds or gained a few pounds. Both are normal at this stage.
