34 weeks pregnant - all you need to know

Your baby is now about the size of a large melon.

Week 34 infographic.

What does my baby look like in week 34?

Your baby's brain is fully developed and they might even be dreaming.

Your wee one is getting pretty snug in there – they're all curled up with their knees to their chest. They can still change position so you’ll still be feeling baby move. Can you work out where your baby’s bum is? What about their back?

If this is your first baby, they may have turned around by now to be head down and pressed deep into your pelvis ready for the birth. This is called ‘engaging’.

When your baby engages, or moves down into your pelvis, any breathlessness you’ve been feeling may ease. This is called ‘lightening’.

Your pregnancy symptoms in week 34

Your breasts

Your breasts will feel heavier and you may feel more comfortable if you wear a lightweight bra at night as well as a more supportive bra during the day.

Pelvic pain

As many as one in five women experience pelvic pain at some point in their pregnancy. The symptoms and pain varies from one woman to the next.

If you’re struggling to cope and Symphysis Pubis Dysfunction (SPD) is affecting your daily life, there is support out there. Talk to your midwife about getting a referral.

Symptoms to look out for

There are some symptoms that you should know about because they could mean that something serious is wrong. Find out what these symptoms are here.

What to do in week 34

Go to sleep on your side if you're not already doing so

When you reach your third trimester, the advice is to go to sleep on your side because research has shown that going to sleep on your back is linked to an increased risk of stillbirth. This advice includes daytime napping and night sleeping. Read more about safe sleep positions in pregnancy

Nutrition for you and your baby

At this point in your pregnancy, you need an extra 200 calories a day to fuel you and your growing baby.

Protect your joints

Because your pregnancy hormones relax your joints in preparation for the birth, it's important to take care when moving around. If you're still doing exercise classes, avoid any high-impact movements (jumping around!).

Make sure you bend your knees rather than your back when you pick things up, and try to avoid carrying anything too heavy.

Pregnancy and swimming

Swimming is a lovely activity all the way through pregnancy. You may want to wear goggles so you can swim with your head down – this keeps your body straighter, which is better for your back.

Try to avoid making too many strong twisting movements, as these could overwork your deep tummy muscles or strain your ligaments.

And avoid the breast stroke, as the kicking action can cause back pain if your spine is not aligned correctly, or pelvic pain if you have symphysis pubis dysfunction (SPD).

What is active birth?

Hollywood often shows women in childbirth flat on their backs in a hospital bed. Active birth is the opposite. The idea with active birth is that you move freely and find labour positions to help manage pain and encourage your baby out. You can find out more from your midwife and antenatal classes.

“Do something to help you feel empowered going into labour, such as hypnobirthing or active birthing. Read up on labour and give yourself a 'tool' to help you feel in control.” Zoe, mum of one

Your antenatal care

Antenatal classes might start around now if they haven't already.

You might want to start looking into the early signs of labour so you know what to expect over the coming weeks.

      I am 34 weeks pregnant , i had an ultrasound. My baby's estimated weight in ultrasound was 1815 gm. Doc told me that it is little less as compared to the actual weight needed at this trimester so i need to take injection for baby's lung mature, plz tell me it is needed or not or is there any effect of this injection in future or if i cant take this injection then there is any problem or not ?...

      I’m pregnant with di/ di twins. At my 34 weeks scan today they said I have low amniotic fluid and my PI is 1.21 (above 95th centile) on twin 1. They then kind of pressured us into agreeing to be induced on Monday but both twins as 5 lb 6oz, much the same length and head measurements. Movement has been normal. But Dr said that if I don’t go in I’m increasing risk during delivery for twin 1. Am I wrong in thinking we’re all well and growing so what’s the need to be induced? Thanks.

    • By Midwife @Tommys on 24 Apr 2019 - 12:14

      Hi Bells Lei
      If you are having regular painful contractions that last up to a minute and are becoming more regular then you should contact your maternity unit for urgent advice.
      If the contractions are similar to Braxton -Hicks as described here-'Sometimes you may feel one or two tightenings in an hour or in a day, but they are usually short, lasting about 20-30 seconds each, irregular and do not continue for a long period of time. Most of the time, women find them to be painless but sometimes they can be uncomfortable.' -then it's ok to work. Please look at the following link for more information-

    • By Emily (not verified) on 28 Jan 2019 - 23:54

      Hello I am 34 weeks pregnant and have experienced severe edema in my feet, legs, thighs, and lower/mid back. This has been checked for preeclampsia but to no avail does anyone have any explanations. I have a healthy BMI before pregnancy and gained around 45lbs in those two weeks I started retaining water. I can barely walk, stand, or even use the bathroom. My husband has to help me get underwear, bottoms, and socks on as with this water retention my body is stiff as a rock and can’t bend. I have been drinking tons of water, pineapple juice, epsom salt baths, and eating natural water reducing foods. What else can I do? I can’t even get my legs into bed because of all this retention! Doctors aren’t concerned!

    • By Midwife @Tommys on 29 Jan 2019 - 15:27

      Hi Emily. I am sorry to hear that you are struggling with swelling in this pregnancy. If you are having regular pre-eclampsia testing, then there isn't too much else that the Dr's or midwives can do. You are doing everything you can do to help reduce it too - I know exercise might seem to much like hard work, but it might help if you could consider it. Swimming is very gentle and supportive on your joints and it might help you get rid of excess fluid without being high impact.
      Have a read of the links below too. All the best, Tommy's Midwife

      hi I'm 33weeks &I'm struggling to sleep at night because it's hot & I'm sweating too much

    • By Midwife @Tommys on 20 Dec 2018 - 14:32

      Hi Maki, In hot climates, pregnant women do find it difficult to sleep. Due to the increased blood supply in pregnancy, women find it difficult to keep cool. Just try to make sure that you are drinking plenty of water and sleep with just a sheet over you.

    • By Rowdy (not verified) on 5 Aug 2018 - 15:29

      I am 34 week pregnant but measuring 32 with sga baby weight 1.8kg . Also I have AFI 21.
      Doctor has given argwell. But don’t know what to expect.
      Is it anything serious ?

    • By Midwife @Tommys on 6 Aug 2018 - 11:02

      I can't say for sure but we usually expect babies to be within 3cm either way of their dates. So measuring 32cm at 34 weeks is within the normal range.

      Am 34 weeks but having pain at pevic bone especially when am walking, It pain me to the extend that I can't walk for some minutes,

    • By Midwife @Tommys on 31 Jul 2018 - 15:52

      It sounds like you have pelvic girdle pain which is caused by pregnancy hormones softening the ligaments between your joints. This is quite normal but you should see your midwife as soon as you can to get referral to a physiotherapist who can show you some exercises and fit you with a support band if required.
      Take care

      Hi,am 35 weeks pregnant.whenever I walk its as if the Virgina is opening hence pain.
      I tested but no prob .the doctor told MI that its weight .need more explanation

    • By Midwife @Tommys on 29 Jun 2018 - 11:24

      Hi Joan,
      For some pregnant women they do describe a feeling of pressure at this stage and it can be very normal. It is usually the weight of the pregnancy and position of the baby which can create this feeling. It is great that you have been seen by your doctor and they are not concerned. If you start to get any tightenings or pains, any bleeding or watery loss or concerns about baby's movements then go to the hospital.
      Best wishes
      Tommy's midwife

    • By Kassi (not verified) on 29 Apr 2018 - 02:30

      Hello I'm gonna be 34 weeks and my doctor is keep saying my baby is small... They said he scored a 6 out of 8 on his bbp test. Should I be worried

    • By Midwife @Tommys on 30 Apr 2018 - 13:57

      Hi Kassi,
      I think this may be a BPP test which is an ultrasound scoring system to evaluate the baby's well being. If this is the correct test it is usually out of 10 and not 8. Have the doctors arranged any follow-up to the scan?

    • By Nia (not verified) on 17 Apr 2018 - 15:15

      34 weeks today doctor said baby has a double echo of the heart and will need to run tests when the baby is born. Was really confused an sad so did not have many questions at the time. Please help what could that mean.

    • By Midwife @Tommys on 19 Apr 2018 - 14:25

      Hi Nia, Thank you for your comment.

      It is difficult to understand what your Dr meant without looking at your hospital notes. What we can tell you is that if some babies are found to have any issues with the heart then they will do further tests after baby is born. Most commonly would be a small hole in the heart but this can close on its own and cause no further issues. As it is unclear if this is what you have been told, we would advice that you contact your midwife or maternity unit to find out in more detail what this means and then you can be full informed of what is happening. Hope this helps, take care, Tommy's Midwives x

    • By Natalia (not verified) on 7 Apr 2018 - 00:57

      Am 34weeks pregnant and finding it hard to sleep on my sides (both) as it give me pains and down my legs anything I can do to help and also in a morning if I move my right leg or streak it it's like it locks and gives me the worst pain for up to around 30seconds do you no why this could be happening?

    • By Midwife @Tommys on 9 Apr 2018 - 15:45

      Hi Natalia, Sorry to hear you are uncomfortable in bed. Have you tried supporting yourself with extra pillows between your legs. Some women find this helpful. Also it can be helpful if you can manage some exercise or stretching during the day. This helps to increase your circulation and make you more comfortable. You can also alternate which side you sleep on or change every hour or two throughout the night. Hope you get some relief and remember that there isn't long to go now. Take care

    • By Sisie (not verified) on 30 Mar 2018 - 18:04

      Hi, I'm 34 weeks, just had a bath and while I was laying sideways it felt like the baby moved towards my upper body towards breasts...I got up and I realised the normal baby position im used to has feels transverse ..I'm really worried....

    • By Midwife @Tommys on 4 Apr 2018 - 10:27

      Hi Sisie
      Baby's can and will move into all sorts of positions. They usually stop doing 180 degree turns after 36 weeks, when ideally they should remain head down. Please do not worry for now about this position that baby has gone into. You have plenty of time for baby to move into a head down position if baby has currently become transverse. If you are concerned about fetal movements, you should go into your local maternity unit day assessment unit/triage to be seen there by a midwife and doctor. Just don't forget to take along your pregnancy notes too! If you wish to chat about this is any more detail, please call us on 0800 0147800
      All the best

      Water broke in 34 weeks this can be problems to affect delivery the baby before 36 weeks.

    • By Midwife @Tommys on 11 Jan 2018 - 10:11

      Hi Dara, if she has not already done so, your daughter in law needs to urgently go to her local maternity unit to be seen by a midwife and obstetric doctor to have this confirmed and to check mum and baby over. They may need to keep her in hospital and potentially induce her labour too.

      What is short structure

    • By Midwife @Tommys on 15 Nov 2017 - 12:13

      Hello, Thank You for your comment.

      It is difficult to answer your question without more details. Do you mean short stature? This means that someone is small in height.
      Or, do you mean short cervix? This is when the cervix starts to shorten in pregnancy and needs to be monitored as this can result in premature birth.

      I'm not sure if you mean either one of these explanations but if your need further advice then please email the Tommy's Midwives on [email protected] Hope this helps, take care, Tommy's Midwives x

      Hello, I'm 34 weeks today. I went for a scan on Wednesday to check the location of the placenta which fortunately has moved well clear. But I was referred to the doctor afterwards as I have far too much fluid. Both the sonographer and doctor mentioned that baby has a very large tummy (it was on the 97th centile compared to about the 50th for head, femur etc). I wasn't expecting this so didn't ask any of the questions I now have. I'm hoping you might be able to help please? I had blood taken for a TORCH test which I understand is to rule out an infection and have the gestational diabetes test on Monday and a further scan and appointment with the consultant on Wednesday. With my three eldest my waters broke as the first sign/start of labour so I'm petrified that will happen and I won't be in hospital and the cord will prolapse. I was already very anxious this pregnancy as in the last year I have had two miscarriages. Is this cord prolapse common? Would I be offered an induction or a c-section? My eldest was born at 32 weeks and my other two 39 weeks (all labours started naturally with waters breaking and they were all relatively straight forward vaginal births). I'm a bit worried about baby having a blockage due to its big tummy but I understand that can be sorted once it is birn. My main concern is the cord prolapse and obviously loosing my baby. I feel like a ticking time bomb and a disaster waiting to happen. Advice much appreciated please.

    • By Midwife @Tommys on 23 Oct 2017 - 11:06

      Hi and thank you for your question. Polyhydramnios is not usually a sign of anything serious and most women with the condition won't have any significant problems and will go on to have a healthy baby. It is good practice to test for infection and diabetes when Polyhydramnios is detected. Although there is a small increased risk of cord prolapse, the highest risk factors are position of the baby. If the head is well into the pelvis before your waters break this will reduce the risks of cord prolapse. Have you got any more planned scans? When will you have results of tests taken? You are welcome to call us on 0800 0147 800 if you want to discuss this further. Take care Tommy's midwives x

    • By Anonymous (not verified) on 26 Oct 2017 - 10:03

      Hello, thanks for getting back to me. I had another scan yesterday and the fluid is a bit higher still but I don't have gestational diabetes or any of the infections they tested for in the TORCH test. The sonographer or the consultant didn't mention the Umbilical Artery PI which looks low. Does this mean my placenta of the umbilical cord arent functioning well? Is baby getting enough oxygen and nutrients?! It's never been a very active baby. It was 0.81 last week and 0.74 this week which is only just over the 5th centile. Please can you let me know what the Umbilical Artery PI is actually measuring? Thanks so much.

      Hi i m 34 weeks pregnant and i gained just 2 ponds weight. i consult to my Dr. and she said it is fine. but i m very worried.

    • By Midwife @Tommys on 19 Oct 2017 - 11:52

      Hi Thank you for your comment.

      Weight gain in pregnancy can be different for every woman. It is important that you are maintaining a health diet and keep exercising. If you have been to see your GP and they have examined you and they are not concerned then try not to worry. As long as you are having plenty of movements from baby and the baby is growing well and not small for this stage in your pregnancy, then it sounds like everything is going well. If you are a health weight before pregnancy then on average you can expect to put on 25-35 pounds during the pregnancy. If you are still worried then please contact your GP or midwife who will be able to give your further advice, they can examine you to check the growth of your baby and if you need an ultrasound scan to measure baby's growth then they can request this for you. Hope this helps, take care, Tommy's Midwives x
