Weeks 16-20

pregnancy adviceAt nearly five months pregnant, your baby is now the size of an avocado.


He or she develops soft body hair known as lanugo and a greasy coating that helps protect the skin, also known as vernix caseosa. If your baby is female, her uterus now begins to form.

Women usually feel their baby’s first movements during the fifth month. It may feel like flutters or butterflies in your stomach or even little taps. Your breasts may have increased by as much as 2 cup sizes by this point!

at 16 weeks pregnant we can take a look at your potty shot for you, if you have paid for a private gender ultrasound scan, and want some reassurance. At 16 weeks gestation, your baby’s genitals are now fully formed and can be identified clearly on ultrasound.

You will have your anomoly scan at some point this month, usually beween 18 – 21 weeks in England. This is a detailed scan which looks for some physical abnormalities in the baby. The sonographer will look in detail at the baby’s bones, heart, brain, spinal cord, face, kidneys and abdomen. The scan allows the sonographer to look specifically for 11 conditions, some of which are very rare. These include;

  • anencephaly
  • open spina bifida
  • cleft lip
  • diaphragmatic hernia
  • gastrochisis
  • exomphalos
  • serious cardiac abnormalities
  • bilateral renal agenesis
  • lethal skeletal dysplasia
  • Edwards’ syndrome, or T18
  • Patau’s syndrome, or T13

In most cases, the scan shows that everything with the baby is completely normal and healthy. The anomoly scan is just to make sure everything is growing and developing as it should. Some times NHS sonographers will tell you the gender of your baby, by looking in between the legs (potty shot).
