24 weeks pregnant - what to expect

Your baby is now about the size of a corn on the cob.

Week 24 infographic.

What does my baby look like?

Have you noticed they are getting into a pattern of sleeping and waking? When you're in bed at night, feeling relaxed and trying to sleep, you might find they're wide awake and wriggling.

Your baby is now said to be ‘viable’. This means that there is a chance that they would survive if they were born now, even though it is still very early.

A baby born at this stage would need a lot of help in the neonatal unit, as their body is still very immature and not ready to cope in the outside world yet.

Your symptoms - what to expect

More vaginal discharge?

A slight increase in vaginal discharge during pregnancy is totally normal, especially if the weather is hot. You may find that it’s a mild-smelling, milky fluid, which is fine.

However, if it is smelly, itchy or a yellowy-greenish colour, contact your doctor or midwife as you may have an infection that needs to be treated. If the discharge is heavy, use a sanitary pad, not a tampon.

Actions to take

My midwife has suggested I have a whooping cough vaccination. Is it safe?

Between 20 and 38 weeks you’ll be offered a whooping cough vaccination to boost your levels of antibodies, which will then be passed on to your baby for protection.

Comprehensive research into the vaccine has shown that it’s very safe, with no ill-effects for pregnant women or their babies.

Can I exercise with symphysis pubis dysfunction (SPD)?

If you’re suffering with SPD, try different exercises until you find one that works. Some women say cycling causes no pain while walking is very painful, others recommend swimming or aquanatal exercises.

If you’re swimming, avoid the breast stroke as this is likely to cause more pain. The key thing to remember is to stop any activity that causes pain.

“Once a week I went to an antenatal exercise class run by two midwives. They helped me to adapt certain moves to accommodate my SPD (symphysis pelvic dysfunction).”

Keep up the calcium

Make sure your diet is rich in calcium, as this is good for your baby’s bone development. Calcium is found in dairy products, oranges, nuts, pulses and broccoli. You should also be taking 10mcg of vitamin D a day in pregnancy, which helps with calcium absorption.

    Can constipation and gas cause a lot of pain? Kind of like menstrual pains but they come and go

  • By Midwife @Tommys on 31 May 2017 - 11:24

    Hi Courtney
    Yes, constipation and gas can cause abdominal pain, however, during pregnancy, it is vital that any abdominal pain, at any gestation of pregnancy, is urgently reviewed by a midwife or obstetric doctor at your local hospital tirage/labour ward/day assessment unit. Please go get checked out if you have no already done so.

    Hi, Without seeing you it would be difficult to reassure you that all is normal. I recommend that you call your midwife or maternity unit even if you were see 2 days ago. Best wishes
