11 weeks old

FETAL DEVELOPMENT
Starting with this week, the baby is now called a fetus. The most critical part of the baby's development is over. This is a period of rapid growth, and the baby is about an inch or so in length at the beginning of the week and will be about 2 inches by the end of the week. The baby's head is about half its length. The eyelids will fuse shut, and the irises will begin to develop. Sometime during this week or the next week, blood will begin to circulate between the baby and uterus and the placenta starts to function.
MATERNAL CHANGES
Your uterus is the size of a small grapefruit alreay! You may find that your appetite is better as your nausea subsides (not true in the case of my mummy) even though certain smells may bother you.
