Week 6

Your baby….

is about the size of a single peppercorn (usually measured from crown to rump as embryo is curled up and makes full length measurements difficult = CRL)
is developing tiny buds that will become arms and legs
brain and nervous system developing rapidly
optic vesicles developing along sides of the head (eventually eyes)
inner ear begins to form, so does the larynx
beginning of digestive and respiratory systems forming
has a heart the size of a poppy seed, beings to beat around this time and can be detected by ultrasound scanning.

You…

for some the full force of pregnancy symptoms may “hit” this week
areola (dark pigment around the nipples) may darken
placenta begins to exchange nutrients and remove waste – two circulation systems are completely separate.
