Your Pregnancy: Week 16

Your pēpi is the size of an avocado.

At week 16, your baby is measuring around 11cm and weighs about 100 grams. They are the size of an avocado now. Their skin is formed, although it’s translucent, and their facial expressions are becoming present. As the kidneys are functioning, small amounts of urine are being passed every 40-45 minutes.

Some people start to feel very faint movements around week 16 onwards, especially if this isn’t your first pregnancy. This is called ‘quickening’ and can be likened to flutters, twinges, or gas bubbles – they’ll feel like proper kicks soon enough.

It’s normal to feel hungrier than usual as your baby is growing rapidly with each new day. See Healthy Pregnancy Nutrition for advice on healthy nutrition during pregnancy.
