- From the top of her head to the bottom of her buttocks, she is about 31 to 42 mm (1.25 to 1.65 in) long. And now, for the first time in your pregnancy, her weight is large enough to measure week by week. She weighs just about 5 g (0.18 oz).
- Her eyes have formed and her facial features are becoming recognizable. Her fingers and toes are also becoming distinct.
- By the end of the week, your baby’s fetal period of development begins. She will grow rapidly and develop specialized parts of her body as the three cell layers — the ectoderm, endoderm, and mesoderm — form.

Is this nature’s way of helping dad feel “pregnant” too?
Fun fact: Chocolate, sweets, and citrus fruits and juices are the top three foods women crave during pregnancy.
