6 weeks pregnant – all you need to know

By the end of this week your baby will have grown to the size of an orange pip.

Week 6 infographic.

What does my baby look like?

Your baby looks more like a tadpole than a baby right now, because their back is curved and they have a tail.

Your baby’s heart started beating at 24 days. There’s a bulge where their heart is going to develop. Even at this very early stage, the heartbeat can sometimes be found on a vaginal ultrasound scan.

There’s also a bump where the brain and head are going to grow. Tiny dimples on this bump soon turn into ears and you can see a thick area where the eyes are going to form.

Your baby is covered with a very thin layer of translucent skin.

Your pregnancy symptoms in week 6

Are you suffering from cramps, constipation or dizzy spells? Find out about 10 common pregnancy complaints (and how to avoid them). 

Morning sickness

One of the hardest things to cope with in the first trimester is morning sickness. Don’t be fooled by the name, the nausea can hit you at any time of the day. Some women get it and some don’t, some get it in one pregnancy and not the next or vice versa. Researchers have not been able to find the cause of it.

Even if you feel terrible, you don’t need to worry about the baby unless you can’t keep anything at all down. Your baby will get everything he needs from you.

'When I had morning sickness, the only thing that made me feel better was drinking tonic water, although it made me throw up. It took me a long time after giving birth to want a G&T again!' 

Louise, mum of two

Morning sickness remedies

These are some things that women have said have helped them, though there is little research to prove that they work. There is no tried and tested morning sickness remedy other than time.

  • Sparkling water
  • Sucking ice cubes
  • Small frequent meals
  • Travel wristbands
  • Foods and drinks that contain ginger (like ginger biscuits, chamomile and ginger tea, ginger ale and crystallised ginger).

If you find you can't keep anything down, speak to a doctor or midwife.

Pregnancy headaches?

Some women suffer with horrible headaches in pregnancy, which can sometimes be caused by hormones or dehydration. Find out more about how much water you should drink in pregnancy.

The following tips might help:

  • Try to rest when you can
  • Find ways to relax, like pregnancy yoga. Our 10 tips to help you relax in pregnancy is a good place to start. 
  • If you need painkillers, make sure you take the recommended dose.
  • Paracetamol is usually safe to take in pregnancy - but not all pain relief is so if you're thinking about a different pain killer make sure to check with your pharmacist.
  • Have a chat with your midwife or GP about pain relief.

If you have a severe headache that will not go away, it’s important you’re checked out by your GP or midwife. 

Tired and emotional?

Many women find that they get extremely tired during the first three months. Your body is working very hard so it's not surprising.

It can be difficult to cope with the tiredness, as you may not want to share the news of your pregnancy yet.

'I was so excited to be pregnant, but it also made me feel very tired. I could have slept all day and then still be tired when I woke up. It’s an exhaustion like nothing you've ever felt before.'

Louisa, mum of two

Just remember that this stage won't last forever, and the deep tiredness you're feeling usually passes when you reach the second trimester. If you can, get more sleep by going to bed earlier.

You may also feel emotional and tearful over little things, and you may find that your mood is suddenly going up and down because of the pregnancy hormones in your body. This is normal, but if you find that you are feeling sad more than you feel happy and the feeling does not go away speak to a midwife or doctor about it.

Are you suffering from anxiety and panic attacks in pregnancy

Smoking and pregnancy

If you’ve just found out you’re pregnant and have been smoking, try not to worry. If you stop smoking now it will make a big difference to your and your baby’s health. We understand it’s a challenge to quit, but there’s lots of help and support out there for you.

Get help to stop smoking.

The risks from secondhand smoke are also high. You might be surprised to learn that 80% of secondhand smoke is invisible and doesn’t smell. This means that if a smoker in your household quits, the benefits to you and your baby are huge, similar to when you stop yourself.

If you’re worried about the amount of secondhand smoke you may be taking in, you can ask your midwife for a Carbon Monoxide (CO) test.

      Congratulations on your pregnancy!
      I would advise contacting your GP for advice on what to do. Alternatively if you are under the care of a specialist clinic please contact them for advice.

      Hi there i am 6 weeks pregnant coming on to my 7th week I have had a stich like feeling on one side of my pelvis it lasted for about 30 mins to 1 hour. this is my first expectance is this anything to be worried about ?

    • By Midwife @Tommys on 13 Mar 2017 - 10:33

      Hi. This isn't usually anything to be concerned about and it is reassuring that it lasted only for a short time. Remember to keep well hydrated and consider a regular exercise regime. If the stitch returns and lasts for several hours it would be sensible to see your GP. Best wishes

      Hi I lost a baby a few year back and I've just found out I'm inmy early stages of pregnancy only 6 weeks I'm suffering from back in the middle of my back should I be concerned I had a scan in Friday and everything was there and I seen the heartbeat but I'm still really worried.

    • By Midwife @Tommys on 3 Mar 2017 - 11:49

      Hi. Apologies for late reply to this post. It is unlikely that this back ache is anything to worry about and good news that you had a positive scan last week. Keep yourself well and look at our page about exercise in pregnancy as this can help to reduce aches and pains. Best wishes

      Hi, I'm 6 weeks pregnant, last year I lost a baby at 11 weeks. Although this pregnancy is stronger my sickness nausea keeps coming and going- is this normal? I'm just just scared of losing another baby and I seem to keep focusing on things and want to put my mind at ease. Thank you

    • By Midwife @Tommys on 27 Feb 2017 - 10:20

      Hi LolaK
      Congratulations on your pregnancy. It is completely normal to be anxious during a pregnancy following a baby loss. Please ensure you get good support from your GP and Midwife in this pregnancy with regular appointments.
      Pregnancy nausea and vomiting can come and go throughout pregnancy. It's absence does not mean that the pregnancy is failing. Fluctuations in pregnancy hormones are mostly the root cause of nausea coming and going. Please feel free to call us on the pregnancyline if you wish to speak to a midwife in more depth and put your mind at ease.
      Take care of yourself.

      Hi, I'm 6 weeks pregnant & have just been talked into having a flu vaccine by my practise nurse. I would have preferred to wait until after 12 weeks or a discussion with a midwife but was advised repeatedly that it was safe in early pregnancy. Now I'm terrified of any damage to the fetus. Can you advise me please? I've also checked the minute ingredients in preparation such as formaldehyde & gentamicin & frightened myself even more! Can you please advise me?

    • By Midwife @Tommys on 17 Feb 2017 - 12:51

      Please try not to worry, the flu vaccine is recommended for every pregnant woman and can be given at any stage in pregnancy. Many studies have shown the vaccine to be safe in pregnancy and there is no risk of harm to the fetus. If you want to talk further then please do email us [email protected]

      Hi i have just come off pills and missed one period did a clear blue pregnancy test came negative I get pregnancy symptoms am I pregnant or not

    • By Midwife @Tommys on 6 Jan 2017 - 09:15

      Sometimes it can be a little early to do a pregnancy test as they may not be sensitive enough to pick up the rise in your hormone levels yet. Or else sometime symptoms are difficult to tell if it is pregnancy or something else. If you have not done so already I would advise to repeat the pregnancy test again. Additionally if you have not done so already to start taking folic acid if you are trying to conceive.

      Hi I'm nearly 7 week pregnant with my 3rd child. Every so often I get a water bloody leaking for my lady bits. Never had it in past. Could your shed a light on this? Thanks

    • By Midwife @Tommys on 3 Jan 2017 - 14:59

      Hi Kirsty
      Any bleeding in early pregnancy needs to be checked out and as this bloody watery discharge seems to be ongoing, it would be advisable to have a medical review to ensure all is going to plan. See if your GP could refer you to the EPU for an early scan or some EPU's allow you to self refer. If you want to chat to one of our Midwives further about this, please ring the Pregnancy Line on 0800 0147 800 (Mon to Fri ) 9am till 5pm.

      Hey I'm 6 wks pregnant and experiencing a slight niggle on my left abdominal side. This is my 3rd pregnancy. Should I be concerned? TIA

    • By Midwife @Tommys on 31 Oct 2016 - 09:20

      Hi there. If the niggle, becomes a pain, then this is certainly worth getting looked at asap. Left or right sided pain in early pregnancy is treated very seriously, due to the risk ectopic pregnancies can pose to the pregnant woman. You may or may not get some bleeding too. Your GP or walk in centre/A&E can refer you to the local early pregnancy assessment unit if you do start to feel pain in that area. Look after yourself.

    • By Midwife @Tommys on 27 Oct 2016 - 12:45

      This clear or whitish discharge is quite normal and happens for a few reasons. During pregnancy, the cervix (neck of the womb) changes and the discharge increases in order to help prevent any infections travelling up from the vagina to the womb. Hope this helps.

      Sorry to ask another question but I don't see my midwife for another couple of weeks, this normal when I wiped after going to the loo I noticed a bit of mucus type discharge. I put it down to the mucus plug being formed but I didn't expect to see any, I'm worried that I'll have a miscarriage, is this to be expected/normal?
      Thank you

    • By Heather (not verified) on 24 Oct 2016 - 13:43

      Hi, I'm 6 weeks pregnant, is it normal not to have many symptoms, I get tired, my boobs hurt and I get cramps. All these come and go some days I don't have any. Is this normal?


    • By Midwife @Tommys on 24 Oct 2016 - 14:13

      Every woman is different. Some have almost no symptoms of pregnancy at all, whilst others get every symptom possible. But yes, they can also come and go on a daily basis. There is a broad spectrum of normal, but what you are describing is completely normal. I hope this eases your concerns.

    • By DMH (not verified) on 10 Dec 2018 - 21:10

      This is helps alot. I don't have all the symptoms, and I notice this comes and goes!

    • By Midwife @Tommys on 24 Aug 2016 - 11:51

      I'm sorry you're feeling so weak at this stage of pregnancy. Do you have an upcoming appointment with your midwife soon?
      At your 28 week appointment you will have the option of a blood test for anaemia. It may be that part of your exhaustion is due to this. If you'd like to speak to a midwife in more detail please give us a call on 0800 0147 800
