Your baby's crown-to-rump length is almost 2.5 inches and she now weighs between 8 and 14 grams! In just three weeks, your baby's size has more than doubled and begins to look a lot more human. Even though you won't be able to feel your baby moving at this time, you can stimulate him and he will squint, open his mouth and move his fingers or toes.


By the end of this week, your uterus is too large to remain completely in your pelvis. You might be able to feel your uterus above your pubic bone. The uterus will continue to grow throughout your pregnancy and will return to its usual size within a few weeks after delivery. Before pregnancy, the uterus is almost solid and holds less than 0.3 ounces. During pregnancy, your uterus will become a thin-walled, muscular container that will hold the fetus, amniotic fluid and placenta. Before pregnancy, the uterus weighs approximately 2.5 ounces and when your baby is born, it will weigh almost 40 ounces!



Because most of the structures are already formed at this point, few will be formed after this time. The structures will continue to grow and develop throughout the remainder of your pregnancy. Your baby's skeletal system now has centers if bone formation in most of the bones. The digestive system is capable of making contractions that push food through the bowels and it is also able to absorb sugar. The pituitary gland beginning to make hormones. You will probably be able to hear your baby's heartbeat with a Doppler at this time!

This week may be the first week that you begin to feel better! Morning sickness often tends to improve or diminish at this time. You may begin to show slightly, especially if this is not your first pregnancy. You will feel more comfortable in loose clothing, such as maternity clothes. In addition to your tummy getting larger your breasts, hips, legs and sides may be getting bigger also.

Your baby develops reflexes and the skin is very sensitive.
The brain is fully formed, and the child can feel pain. the baby may even suck his thumb. The eyelids now cover the eyes, and will remain shut until the seventh month to protect the delicate optical nerve fibers.
