Your 9 months Pregnancy You're 19 weeks pregnant What incredible things can you look forward to this week? 1 of Ad break How big is your baby?Your baby is about 15cm long – around the size of a baby courgette!Now find out how your baby is growing… How is your baby growing?She already has the protective covering of the fine hair, lanugo, on her delicate skin and now begins to produce vernix, a white waxy covering, to coat her skin and keep it moisturised in her watery environment. You’ll probably be able to see traces of this vernix when you first hold your baby after the birth. Things are about to slow down a little growth-wise. Your baby’s nerve cells for taste, feeling, seeing and hearing are all growing more complex and your baby will be able to hear noises outside the womb, not just the noises from your own body. (Internal noises might be your tummy rumbling or the general internal roar of your blood flowing round your veins, your digestive system and so on, all amplified through the amniotic fluid.Don't worry that these are loud - your unborn baby is used to them!) She will gradually learn to recognise your voice and that of your partner, and noises that she becomes familiar with now will often be soothing for her after birth. So play music you’re happy to listen to over and over again. Now find out what your body is doing… What’s happening to your body?You may notice a dark line appearing running down the middle of your tummy to your pubic bone. This is called the linea negra. It’s actually always been there but is usually the same colour as your skin. During pregnancy your skin pigmentation changes, and your line negar becomes much darker. Like other colour changes to your skin, it will gradually disappear once your baby is born. Your uterus may have grown level with your navel, and you might experience some discomfort as it presses against your belly button, pushing it outwards. Overall though, this is a great time in pregnancy, you’re no longer feeling sick and drained of energy and you’re not yet big and heavy, so it’s a good time to keep up with your social life. Remember to be careful about food safety. Learn more about what symptoms to expect this week and check out our week by week pregnancy guide...
