Your baby this week

- Movements become smoother and more coordinated.
Your body this week

- Mild swelling in the hands, feet and ankles is common.

What to expect
The last stretch asks a lot of your body. Sleep gets harder, movement slows down, and your appointments become more frequent. With 7 weeks to go, focus on rest, on knowing the signs of labour, and on having your bag ready.
Tips for this week
- Put your feet up when you can to ease swelling.
- Sudden swelling in the face or hands needs to be checked the same day.
- Start getting used to sleeping on your side, ideally the left.
