Week 25 Pregnancy
You are 25 weeks pregnant and in your second trimester. Your baby is about the size of a rutabaga. This week's key development: Building Reserves. NHS note: Routine care.
Baby's Development
Your baby is about the size of a rutabaga.
Building Reserves — Your baby is gaining weight more rapidly now, and fat stores are developing steadily. Their hands are fully formed and sensitive to touch. You may notice your belly moving as your baby responds to sounds, light, or even what you've eaten.
Your Symptoms
- Haemorrhoids
- Heartburn
- Restless legs
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.
NHS Appointments
Routine care. You may be offered a glucose tolerance test (GTT) if you're at risk of gestational diabetes.
Practical Advice for Week 25
Nutrition
- Continue vitamin D daily.
- Eat smaller, more frequent meals to manage heartburn.
- Include plenty of fibre — prunes and whole grains help with constipation.
- Calcium-rich foods remain important as your baby gains weight rapidly.
Exercise
- Keep up with pelvic floor exercises — they're vital for labour and recovery.
- Walking, swimming, and gentle cycling are all still safe.
- If haemorrhoids are bothering you, gentle exercise and fibre help.
- Avoid high-impact activities — your joints are loosening due to relaxin hormone.
Wellbeing
- Restless legs at night are common — try stretching, massage, and warm baths.
- Heartburn can be managed with antacids (speak to your pharmacist for pregnancy-safe options).
- Haemorrhoids are unpleasant but very common — ice packs and witch hazel pads can help.
- Prioritise rest — your body is working incredibly hard.
Preparation
- You may be offered a glucose tolerance test (GTT) if you have risk factors.
- Start packing your hospital bag — a little at a time.
- Research infant feeding — breastfeeding support, formula options, or combination feeding.
- Check your maternity leave dates with your employer.
Tip of the Week
Eat smaller meals more often to help manage heartburn and indigestion.
