Every pregnancy is different. You may experience all, some, or none of these symptoms — and that's completely normal. If anything concerns you, speak to your midwife.

Practical Advice for Week 29
Nutrition
- Continue vitamin D daily.
- Eat calcium-rich foods to support your baby's rapidly hardening skeleton.
- Constipation can worsen — eat high-fibre foods and drink plenty of water.
- Small, frequent meals help manage heartburn and keep energy levels stable.
Exercise
- Continue gentle exercise — walking, swimming, and prenatal yoga.

- If heartburn worsens during exercise, try walking at a slower pace.

Wellbeing

- If movements decrease or change pattern, contact your maternity unit immediately.

- Take time each day to rest and connect with your baby.
Preparation
- Routine midwife care — blood pressure, urine, and fundal height measurement.
- Finalise your birth plan and share it with your birth partner.
- Research what happens if you need an emergency caesarean — being informed reduces fear.
