At 19 weeks pregnant, your baby is about 11cm (4.3in) long. Her legs are longer than her arms and she can wriggle and stretch.
By 19 weeks pregnant you should have gained between about 2.7-6.3kg (6-14lb), of which only about 200g (7oz) is your baby! The rest is made up of your placenta (170g/6oz); amniotic fluid (320g/11oz); your uterus (320g/11oz) and your breasts, which have increased in weight by about 180g (6.3oz) each.
What's happening to your nipples?
At 19 weeks pregnant your areola (the dark area around the nipple) is getting larger and darker. This should return to normal eventually, but could last until your baby is one year old. Yours aren't the only nipples that are changing: your baby's are also now visible.
Did you know?
The darker your nipples are, the easier it is for your newborn baby to find them and latch on when feeding.
