17 weeks pregnant
Your baby’s development
Your baby is now about 17cm long. Their kidneys are now working well so, like you, they’re weeing several times per day. Their urine is filtered back to you through the placenta and is managed by your body. Your baby’s hearing is also getting much better, so you may notice that they respond to sudden loud noises from the outside world.
You & your body
Constipation during pregnancy is a common problem and may be more troublesome from now on as your baby gets bigger. A diet rich in fibre can help, so include high-fibre foods at every meal and try to snack on fruits and vegetables between meals.
Bran or oat cereal makes a good fibre-packed breakfast and during the rest of the day, you can top it up with wholegrain bread, wholemeal pasta, pulses, or perhaps a jacket potato. Remember that plenty of fluids are vital to ensure that you avoid constipation, so have about eight glasses of water including fruit juices or smoothies throughout the day.
