Your baby measures about 34 cms and weighs around 800 grams. Your baby's lungs are developed but immature. To prepare them for life on the outside, your baby breathes in amniotic fluid. This is thought to bring on hiccups - you'll feel them as rhythmic taps in your tummy. Cute.
See how your baby grows in our week by week image gallery.
If you went into labour this week - with the right care - your baby would have a good chance of survival. You've probably already thought about the birth. But what about your birth partner (or partners)? It doesn't have to be your baby's father - or only him. You could have your mum there, a close friend, or a doula. But bear in mind that some maternity units limit numbers, so it's probably best to stick to a duo, rather than a gang!
If you're worried about the shape or size of your nipples don't be. Babies manage to breastfeed perfectly well whatever your nipples are like. If you're worried, ask your midwife or a breastfeeding counsellor.
Pregnancy health: you may be offered a blood test to check for anaemia around this time. Anaemia can make you tired and affect the health of the placenta, so if you're anaemic, it's important to boost your iron levels with supplements (your midwife will arrange these for you).
