19 Weeks- Development

Your Baby This Coming Week

Your baby weighs about 9 ounces (260g) and measures about 5.6 to 6.4 inches (14 to 16cm) from crown to rump.

Her skin is thickening and developing multiple layers- the epidermis and the dermis, the deeper layer where it will form fat. Your baby is now also developing a waxy protective coating for her skin called vernix caseosa. The vernix protects your baby's skin which is continuously submersed in amniotic fluid. Vernix, which is particularly thick around the eyebrows is held in place by tiny downy hairs called lanugo.

Your baby can now grip with her fists. Toenails and scalp hair are growing.

At this point, it may be possible to determine the baby's sex by ultrasound, if the baby cooperates, but the ultrasound technician will rarely guarantee the sex based on the ultrasound results as mistakes are sometimes made at an early ultrasound.

You can hear the baby's heartbeat with a Doppler ultrasound device or a stethoscope.

Your Body This Coming Week

Congratulations! You are now halfway through your pregnancy!

You may have a strong sense of well-being. You should be able to feel your baby moving in your uterus several times in a day.

Your bellybutton may become flat or may even actually pop outwards. It will probably continue to darken also, but will return to its usual pigmentation after birth. The top of your uterus (the fundus) is just below your navel.

As your uterus expands, you can expect it to put increased pressure on your lungs, kidneys and stomach. This increased pressure can result in breathlessness when you exert yourself physically. It may also cause indigestion and the need to urinate more often. Your expanding belly may also cause stretch marks on your belly. The stretch marks will probably fade considerably after your baby's birth and even more as time passes.

You may continue to have mood swings and anxiety, but this may begin to decrease. If you have been experiencing absentmindedness, it may continue.
