FACTS: The baby is still smaller than your little toe yet has all its main organs in a rudimentary form and in the correct positioning. A brain is already visible through the rice-paper-thin skin revealing every little branching blood vessel beneath.
FACTS: During pregnancy the amount of blood in your body increases 30-50 per cent to nourish and supply the baby with oxygen.
FACTS: The placenta is now fully-formed and functioning. It can now supply all the oxygen and nutrients to the growing baby via the umbilical cord.
Conception On its arrival, it becomes known as a blastocyst and floats freely within the womb cavity for about three days before embedding in the wall lining and linking to the blood supply.
Spinal Cord Your baby’s spinal cord and the brain are now almost complete and the head is beginning to look more human-like. Measuring about 1.3cm long, its limb buds have grown into tiny arms and legs with small ridges that will develop into fingers and toes.
FACTS: Your baby now weighs more than the placenta and is covered in swirls of soft down-like hair covering the body called lanugo.
Foetus Your baby, now called a foetus, has obvious elbows, wrists, ankles and clearly visible fingers and toes. It measures between 3-4.5cm in length and its external sex organs have begun to form.
Genitals Your baby’s genital swelling becomes a penis or clitoris. Its neck elongates and the head raises up, looking more human-like. The womb environment, like a bag of water, cushions the baby from bumps, keeps it at a constant warm temperature and allows freedom of movement.
