What's happening in my body?
It's great for you and baby to stay active, but some exercises, such as running, could become uncomfortable.
This is because the hormone "relaxin" loosens up your ligaments, leaving your back, knees and ankles without their usual support.
Tips for better sleep
Not getting enough sleep in pregnancy can be very frustrating. You could try these tips for better sleep:
- practise beditation – a mixture of meditation and gentle stretches designed to help you drift off
- sleep on your side
- use pillows to support your bump and any aching muscles
- try sleeping with a pillow between your knees
The NHS website has remedies for sleep problems during pregnancy.

What does my baby look like?
Your baby, or foetus, is around 15.3cm long from head to bottom. That's approximately the size of a beef tomato.
Their adult teeth are starting to grow, and they are lining up behind the first set.
Your baby's putting on weight, getting ready for the birth in about 21 weeks' time.
