Week 28 Pregnancy
You are 28 weeks pregnant and in your third trimester. Your baby is about the size of an aubergine. This week's key development: Hello, Third Trimester. NHS note: 28-week midwife appointment.
Baby's Development
Your baby is about the size of an aubergine.
Hello, Third Trimester — Your baby's eyes can now open and close, and they're beginning to develop a sleep-wake cycle distinct from yours. The brain is growing rapidly. You may feel short of breath as your uterus rises and presses against your diaphragm — completely normal.
Your Symptoms
- Braxton Hicks
- Back pain
- Frequent urination again
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
28-week midwife appointment. Anti-D injection offered if you are Rhesus negative.
Practical Advice for Week 28
Nutrition
- Continue vitamin D daily.
- Eat iron-rich foods and consider an iron supplement if your blood tests show low levels.
- Calcium is vital — your baby's bones are hardening rapidly.
- Drink plenty of water — dehydration worsens Braxton Hicks contractions.
Exercise
- Third trimester exercise should feel comfortable — modify as needed.
- Birth ball exercises help your baby into a good position and ease back pain.
- Walking remains excellent for maintaining fitness and preparing for labour.
- Avoid lying flat on your back — your baby's weight presses on a major blood vessel.
Wellbeing
- Braxton Hicks are practice contractions — irregular and painless, they're completely normal.
- Frequent urination returns as the baby presses on your bladder again.
- Back pain may intensify — use a pillow between your knees when sleeping.
- Get to know your baby's pattern of movements — report any changes to your midwife immediately.
Preparation
- 28-week midwife appointment — blood tests and anti-D injection if Rhesus negative.
- If you haven't started your hospital bag, begin now with the essentials.
- Confirm your birth partner and discuss your preferences together.
- Research your MATB1 certificate — your midwife provides this after 20 weeks for your employer.
Tip of the Week
Get to know your baby's pattern of movements. If they change, contact your midwife immediately.
