Progress

Here's the Baby Center report for this week: 

Pregnancy: Week 8 : 

How your baby's growing: 

Technically your baby is still considered an embryo. That's because he has something of a small tail, which will disappear in the next few weeks. But that's the only thing getting smaller. The heart and brain are becoming more complicated, the eyelid folds are forming, the tip of the nose is present, and the arms now bend at the elbows and curve slightly over the heart. 

How you're changing: 

You may not look or even feel pregnant, but your uterus is expanding to accommodate its new resident. Before pregnancy your uterus was the size of a clenched fist; now it's as big as a grapefruit. As your uterus grows you may feel some abdominal cramping and mild twinges.
