Pregnancy Week 14
Crown to rump, your baby is about 8cm long and weighs about 40g. Its body is now growing faster than her head. This week, her parchment-thin skin is starting to cover itself with ultra-fine, downy hair (lanugo) that usually disappears before birth. Though her eyebrows are beginning to grow and the hair on top of her head is sprouting, this hair may change in both texture and colour after birth.
Thanks to brain impulses, your baby’s facial muscles are getting a workout as her tiny features form one expression after another. About now, your baby can grasp, squint, frown, and grimace. It may even be able to suck the thumb. Meanwhile, your baby’s kidneys are producing urine, which she releases into the amniotic fluid around her. This will be there up until birth.
You should have had your first two ultrasound scans by the end of this week. A dating scan is offered between 10 and 13 weeks plus six days. And a nuchal translucency scan, which checks whether your baby is likely have Down’s syndrome, is offered between 11 weeks and 13 weeks plus six days.
Note: Every baby develops differently. This page is designed to give a general idea of how a fetus grows in the uterus.
