Baby is now about the size of a blueberry - 1.2cm...
Your baby's brain is growing fast, generating about one hundred new nerve cells every minute as the nervous system takes shape. The over-sized head isn't just large and oblong anymore; it's actually a little bit pointy. Eyes and ears are the most visible features on your baby's head, but the mouth and tongue are also beginning to form.
The arms and legs are emerging and joints start to form. The tiny receding tail bud is now starting to be overshadowed by the growth of legs, which have knees and the beginnings of toes. The ends of the arms are flattening out to become to beginnings of tiny hands.
A permanent set of kidneys is now in place and will start working in the next week or so, as your baby starts to produce urine. The urine will be excreted into the amniotic fluid.
It is at this stage that there is some variation between a boy or a girl although their genitals won't be visible on a scan.
Your breasts are growing - some women have gone up a whole cup size by week 7 – and they are likely to be feeling tender and achy. Your nipples may feel extra sensitive and the areola (the dark area around the nipples) is darker and larger. The bumps you may have noticed in week 5 have become more pronounced. These are called Montgomery tubercles and are sweat glands that help to lubricate the nipples. All these changes are taking place because your breasts are starting to prepare for breastfeeding.
