24 weeks pregnant - what's happening

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's happening

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.

    I'm 24 week and my baby is 22kg and my midwife says the baby is very small. please what should I do

  • By Midwife @Tommys on 5 Dec 2017 - 12:41

    Dear Stella,

    Thank you for posting. Have you had a recent scan? Is this is the estimated fetal weight of your baby? If the midwife is concerned you should be referred to your consultant and a plan of care and extra scans organised for the remainder of your pregnancy. We can discuss this in more detail if you give us a call on 0800 0147 800 or email us [email protected]

    Best wishes,

    hi, i am 24 +1 and last night i had the most agonising stomach pain, which only lasted for about 15/30 seconds but felt like hours, and it happened for about 10 mins repetitively, is this braxton hicks or should i have gone to hosptial? (i am R neg blood type if that makes a difference)

  • By Midwife @Tommys on 4 Dec 2017 - 15:40

    Hello. Can I assume that you are feeling well today and that you are feeling good fetal movements? It is unusual for Braxton hicks to be painful so there may be a different cause here. Are your bowel movements normal? Hopefully you won't experience it again. You only need to consider your Rhesus status if you have a bleed. If you are still unsure and not able to get hold of your midwife you can call us on 0800 0147 800. Best wishes

    iam 24weeks pregnant and i
    usually have a heart burn,what do I do? although its my second pregnancy. what do I take to calm it down

  • By Midwife @Tommys on 2 Nov 2017 - 14:10

    Hi, Thank you for your comment.
    Heart burn can effect many women in pregnancy and there are remedies that can be used to help this. An over the counter antacid medication like Gaviscon may help. You can buy these from the chemist or you can go and see your GP who will be able to give you a prescription for some medication to help with heartburn and you should get free prescriptions in pregnancy with your maternity exemption card. Hope this helps, take care, Tommy's Midwives x

    Always tired don't know what the cause

  • By Midwife @Tommys on 26 Oct 2017 - 12:54

    Hi, Thank you for your comment.

    Being tired in pregnancy can be very normal as your body is working hard to grow your baby, but if you are feeling that you are tired all the time and this is not getting better then it could be a sign that you are anaemic. Having low iron levels in pregnancy can happen and it is easily treated with iron tablets. You can always see your GP or midwife about this and they can do a simple blood test to check your iron levels and prescribe treatment if this is needed. Hope this helps. Take care, Tommy's Midwives x

    hi iam 24 week pergant and I have a tsc problem it is save for my baby

  • By Midwife @Tommys on 23 Oct 2017 - 11:57

    Hi, Can you clarify what you mean by tsc problem? Thanks

  • By Anonymous (not verified) on 21 Sep 2017 - 21:55

    Hi Tommy. I had an ultrasound scan @ 24 weeks and my sonographer said it's a girl. So I'll like to find out its there any chance it could be a boy. Don't know if scans are 100% accurate.

  • By Midwife @Tommys on 22 Sep 2017 - 11:46

    Most scans are quite accurate at showing the gender of your baby however they are not 100%, it depends on the position of the baby and the view that the sonographer was able to get. The only 100% way of knowing if when the baby is born.

    I find difficult in sleeping is it safe to sleep on my back

  • By Midwife @Tommys on 19 Sep 2017 - 16:20

    Hi Comfort,
    thank you for posting. I'm sorry you are having a difficult time sleeping at the moment. At 23 weeks it would be good to start getting into the habit of lying on your left side to sleep. Gathering all your pillows to make yourself comfortable for sleep. After 16 weeks the weight of your pregnant uterus can affect blood flow from your lower body to your heart and slow placental blood flow to your baby if you lie on your back to sleep. After 28 weeks it is important to avoid sleeping on your back as there is a proven increased risk to stillbirth
    Please don't panic if you do wake up on your back just try to get yourself back into a left side position to reduce your risk after 28 weeks.
    Best wishes

    Hi Tommy, I am over 24 weeks pregnant now but still feel no movement of my baby. However, the scan show that everything is normal. What should I do? Thanks

  • By Midwife @Tommys on 16 Aug 2017 - 10:27

    Hi Vratz. Congratulations on your pregnancy. If this is your first pregnancy, it can take a little longer for you to recognize fetal movements, as you have not felt this before. But by now, usually you can feel something.
    Sometimes an anterior placenta (a placenta at the front of your bump) can reduce how much you are able to feel fetal movements as it cushions the sensations. You can ask your midwife where you placenta is next time you see her.
    If you have a higher than average body mass index (ie, you are overweight) this can contribute to feeling your baby less. The more adipose tissue (fat) there is around the tummy area, the more this can impact how much movement is felt. You can discuss this with your midwife too if you do have a raise BMI.
    But it is also sensible to err on the side of caution and continue to be seen regularly if this lack of felt movement persists. You are always well within your rights to take yourself into your locaL day assessment unit, triage or labour ward to be checked for fetal movements. Please take care and feel free to contact us again if you have further concerns

  • By Anonymous (not verified) on 24 Aug 2017 - 11:07

    yes, its my first and higher BMI. I had my apt. with a midwife and she said everything seems to be progressing fine. I'm just craving to feel that kick (in absence of any other craving). Thank you so much for reassuring and your response.

    Hi Tommy,Just think thinking if ultra sound can be false at 22 weeks about the gender of the baby.Am doing great and baby is fine also.

  • By Midwife @Tommys on 24 Jul 2017 - 15:36

    Hi. Great to hear that your baby is doing well. You are correct that it is not possible for the sonographer to be 100% certain when confirming the gender of the baby by scan at 22 weeks. The main purpose of the anomaly scan is to check for any abnormalities in the baby. Best wishes

    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.

    I had a bleed on Tuesday had to stay in over night bleeding has stopped now am feeling loads of pressure when I stand and walk around is this normal?

  • By Midwife @Tommys on 24 Nov 2016 - 12:06

    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

  • By Midwife @Tommys on 14 Nov 2016 - 10:41
