22 weeks pregnant - what's happening

Your baby now weighs one whole pound! From around now, they start to weigh more than the placenta. They’re about the size of a papaya.

Week 22 infographic.

What does my baby look like?

Over the next few weeks, your baby’s taste buds will continue to develop and they’ll be busy practising swallowing in readiness for life outside your womb.

What you eat now could affect the flavours your baby prefers after they’re born, so eat plenty of healthy food.

Your baby’s lungs are not yet ready for life outside the womb but they’re developing fast. Even though they can’t breathe in the womb, your baby’s practising breathing movements for life outside.

They get all their oxygen from your blood via the placenta until they take their first breath after they're born.

Smoking decreases the amount of oxygen in the placenta, so it’s very important to stop if you’re still smoking.

Your symptoms - what's happening

Spotted a stretch mark?

Stretch marks are pink or purple marks that appear on your bump, or possibly boobs and thighs. They eventually fade to silver.

Hormonal changes during pregnancy make your skin more prone to stretch marks as your bump grows. Creams that claim to prevent or stop them are unlikely to have any effect, because they can’t penetrate deep enough to where the damage is.

However, it won’t hurt to very gently massage your bump with nice oils or creams if you find it relaxing, and might make you feel better about your new ‘badges of honour’.

Keep an eye out for swollen feet and hands

If rings on your fingers feel a bit tight or your shoes a bit snug, this is probably due to the increased fluids in your body, known as oedema.

However, get medical advice from your midwife, doctor or the hospital straight away if you have the following signs:

  • Sudden severe swelling
  • Swelling on your face as well as your hands and feet
  • Bad pain under your ribs
  • You are vomiting
  • You have a severe headache or problems with your vision.

These symptoms can be signs of pre-eclampsia.

Actions to take

Is it safe to diet during pregnancy?

Pregnancy is not the right time for a weight-loss diet. It is a time to eat well for both you and your baby. If you try to lose weight, you and your baby may miss out on nutrients that you need to stay healthy and strong.

If you’re concerned about weight gain, remember that if your diet is healthy, much of what you put on will be lost with the birth of your baby and the placenta.

What is BMI and why does it matter?

Don't forget your pelvic floor!

Make sure you give your pelvic floor muscles a workout as part of your daily routine. Toning up your pelvic floor muscles will help you ease your baby out and recover more quickly after the birth.

They will also help stop you weeing by accident, especially when your growing baby starts to press on your bladder.

“I exercised throughout both my pregnancies, right up until my due date. I was a lot more tired in the second pregnancy, because I was running around after my daughter, but I always did something active because it made me feel better.”

Aileen, mum of two

    Am 20 weeks and the doctor said I have Anterior placenta .please is my baby safe?

  • By Midwife @Tommys on 29 May 2018 - 11:15

    Hi Beatrice
    Having an Anterior placenta is not a concern, it just means that your placenta has grown towards the front of your bump. Many placenta's grow towards the back of your bump - near to your back inside- these are called posterior placenta's.
    Anterior Placenta's can make you feel fetal movements a little less as baby is cushioned by the placenta. If you are ever worried about fetal movements being reduced from what you feel usually, then you should go to your maternity unit to be reviewed by a midwife and doctor asap - for every episode of reduced fetal movements that you have felt .
    Please take good care of yourself

    My placenta is low lying and covering my cervix but was just wondering if I am able to go swimming?

  • By Midwife @Tommys on 15 Jan 2018 - 16:41

    This depends on how many weeks pregnant you are and whether you have been diagnosed with placenta previa. If you are still early in your pregnancy, there is a chance that the placenta will move up out of the way but if you have been diagnosed with placenta previa major, you would be advised to avoid strenuous exercise. This page helps explain

  • By Victoria (not verified) on 16 Jan 2018 - 09:49

    Thank you for your response.

    Im 22wks +3 days. Previa hasn't been mentioned just low posterior placenta is written in my notes...

  • By Midwife @Tommys on 17 Jan 2018 - 13:19

    Hi Victoria
    It may be that they are keeping an eye on the placental site, it doesn't sound like its covering the cervix, which is praevia. You may need extra scans for this over time. So feel free to ask your midwife at your next app.
    Take care

    Is that normal lowlyibg placenta at 21 weeks but still they can see cervix..please share your worried..Thanks

  • By Midwife @Tommys on 13 Dec 2017 - 13:32

    Hi, Thank you for your comment,

    It can be common to go for your detailed scan at around 20 weeks and the placenta is found to be low lying. What is reassuring is that it is not covering the cervix and as the pregnancy grows the placenta should move up the uterus and out of the way. You should be given another scan later on in your pregnancy so that they can rescan you to see if the placenta has moved. If you are concerned then please contact your midwife to discuss this but try not to worry, it can be common and there is nothing to suggest that your placenta wont move during your pregnancy. If you have any bleeding in pregnancy then we would advice that you contact your local maternity unit, this is always something to be mindful off with a low lying placenta. Hope this helps, Take Care, Tommy's Midwives x

    Im 22 weeks with anterior placenta, I've not really felt any movements because of this.
    At what point should I get worried things aren't right and contact my midwife?

  • By Midwife @Tommys on 30 Nov 2017 - 14:11

    Hi, Thank you for your comment.
    Having an anterior placenta may mask some of your baby's movement but if you are concerned at all then we would advise you to call your midwife as soon as you feel concerned about anything. They will be able to listen in to your baby and give you reassurance. Take Care, Tommy's Midwives x

    I had circlage at 19weeks because my cervix opens at 24weeks my baby boy was alive for 2dys & past on now im 22weeks bt i feel like my baby is kicking the stitch and i feel mild pains is it normal? please help im just nervous

  • By Midwife @Tommys on 17 Aug 2017 - 16:29

    Hi, it is completely understandable that you are feeling so nervous in this pregnancy given what you have been through. It is lovely that you are feeling your baby move about however they would not be able to kick so much so that the stitch comes out or on your cervix so your go into labour. With regards to the pains that you are feeling I would need a little bit more information such as the type of pain, how often you are feeling them etc.? Also some pain can be due to a urine infection so ensure that you have had your urine tested recently by the midwife or doctor. If you are having any vaginal loss, and/or pains are on going then do ring the maternity unit for advice.

  • By Midwife @Tommys on 1 Aug 2017 - 15:53

    Hi Siobhan,
    it does sound like you are busy with your little ones. Could you call your unit and see what they advise. I fully appreciate that it would take some time to organise childcare. It is good to know that your bladder has settled put a pad on and monitor if there is any loss and call the unit an hour after that. If you have a thermometer at home I would also just check to see that your temperature is normal (36.1-37.2) also monitor for any odour from the discharge.
    Take care of yourself

    Thanks for your advice, I did go to my local day assessment unit (as the frequency I needed to go to the toilet increased again) and I do have some sort of infection, they'll get the results in a couple of days and prescribe whatever antibiotics are necessary. A doctor checked and my cervix was still closed, waters still intact, thank goodness! A massive relief, thanks so much for advising me to go, the midwife was really nice and I didn't feel I'd gone in unnecessarily. I have had two miscarriages in the past year so feel very anxious a lot of the time so it's difficult to know when I'm being concerned for a reason or not. Thanks very much, it's lovely to have the peace of mind and treatment for an infection. Kind regards, Siobhan

  • By Midwife @Tommys on 1 Aug 2017 - 13:31

    Hi and thank you for posting. Going to the toilet every 15 minutes seems quite excessive and tedious. Although you don't have any pain, the sheer number of times you are needing to go to the toilet would make me think that we need to exclude both a urinary tract infection and ruptured membranes in view of your first baby being premature. As you mention the wet underwear could just have been pregnancy discharge which can be increased especially in the warmer weather.
    As you are over 18 weeks you can be seen at the Day Assessment Unit at your unit. Look on the front of your notes and contact them now. They will check your urine and may perform a speculum examination to see if your waters have gone.
    I hope all is well but please go in to be checked for your peace of mind and let us know how you get on.
    Warm wishes

    Hi again, thanks for getting back to me. Fortunately the frequency of urination stopped pretty much after I posted to you! So that must be several hours ago. Would you still think I need to be seen? I haven't had anymore watery discharge (since about 9pm last night, which I mentioned previously). My husband is away and I have three little children at home with me, that said if you'd advise a trip I'd do anything to make sure this little one stays safe regardless of the 'hassle' of sorting childcare! My second and third babies were both 39 weeks, by the way, just the first was early at 32 weeks. Thanks again, Siobhan

  • By Siobhan (not verified) on 1 Aug 2017 - 10:43

    Hello, I'm 22 weeks and this morning I keep needing the toilet! Maybe every 15 minutes. It doesn't hurt and it's all clear but if I was out somewhere it would be so inconvenient. Is this normal at this stage? I'm feeling well otherwise although yesterday I had two incidents (one about 10am, one about 9pm) where my underwear felt wet and I know it wasn't urine. I was fine and dry inbetween and have been dry since. I'm presuming this is just discharge and not my waters leaking. My first pregnancy baby came at 32 weeks and when my waters went they didn't stop flowing. Thanks so much for your help.
