Your body this week

What to expect
Early pregnancy can feel invisible from the outside and very loud on the inside. Symptoms come and go from day to day, and that is normal. With 34 weeks to go, the priority this week is rest, gentle food and your first antenatal appointment.
Tips for this week
- Eat small, frequent meals; an empty stomach makes nausea worse.
- Drink water through the day; dehydration worsens tiredness and headaches.
- Book your first antenatal appointment — most take place between weeks 8 and 12.
