12 weeks pregnant – all you need to know

It’s been a busy few weeks: Everything is now in place - the organs, limbs, bones and muscles are in place and growing.

What does my baby look like in week 12?

Your baby, although tiny, is now fully formed. They are about the size of a plum.

From now on, your baby is going to grow, grow, grow! The placenta is also fully developed. The cartilage skeleton is beginning to turn into hard bone. Even though you can’t feel it yet, your baby is moving, waving and dancing. They can also swallow.

Pregnancy symptoms in week 12

Congratulations - you’ve made it through the tiring first trimester. You’re a third of the way through and you should have more energy in the second trimester.

Are you drooling in your sleep?

Excess saliva is one of pregnancy’s little surprises - it’s totally normal and probably caused by hormones.


Some women find they’re more prone to nosebleeds during pregnancy.

What to do in week 12

Your first scan

Between week 11 and 13+6 you’ll be offered an ultrasound scan - and your first chance to see a glimpse of the tiny life inside you! It’s sometimes known as the dating scan and the sonographer (the person who scans you) will be able to check whether your due date is accurate by measuring the size of your fetus.

The scan happens in the hospital, and most offer a copy of the picture of your baby from your scans. You may need to pay for this, so take some money with you to your scan appointment. They are printed on thermal paper, so don't laminate them!

“It was such a relief to know everything was okay and get a photo of our baby. At that point, you know it's real and it's happening.”Emma, mum of one

It’s also worth asking your midwife about antenatal classes in your area. Your hospital or birth centre is likely to offer free NHS classes, in which they cover the birth, birth plans, breastfeeding and early days with your baby.

Antenatal classes won't usually start until mid- to late pregnancy but they can get booked up quickly so it's worth signing up for them now.

If you haven't yet been given a date for your booking appointment or scan, contact your doctor or midwife.

Deciding where to give birth

You can start thinking now about where you’d like to give birth. It could be a midwife-led birth centre, a hospital birth centre or a home birth.

The choices that you have will depend on where you live and whether you have any health complications.

If you decide early on in your pregnancy where you would like to have your baby, you can change your mind later.

Staying safe

There are a few important symptoms that you should look out for in pregnancy because if you have them they could indicate a more serious problem. Find out what the symptoms to look out are here.

Booked a check-up at the dentist yet?

Pregnancy hormones can be unkind to teeth (and you’re more likely to suffer from bleeding gums) so you need to take extra care of both. Going to the dentist is free in pregnancy and for a year after your baby is born. Don’t forget your exemption card.  

Telling people about your pregnancy

After week 12, the risk of miscarriage becomes lower and less of a worry.

If you haven't told friends, family and colleagues about your pregnancy yet, you may be thinking about doing it around now.

If you decide to tell your employer about your pregnancy now, ask them to do a risk assessment to ensure your workplace is safe and comfortable for you and your baby.

      I'm also 12weeks gone today thanks to your up dating app for keeping me posted and informed about everything I need to know per week as the pregnancy progresses. I suffered morning sickness at early weeks of my pregnancy but I'm much better now.

      Hi am 12 weeks and know how that feels. What helped me is ginger.
      Chewing fresh washed ginger stopped me from having much saliva and vomiting. If you can, try it.

    • By Kklau (not verified) on 15 Jan 2020 - 23:13

      Everything you're describing sounds totally normal at this phase in your pregnancy. Some women have a ton of symptoms and some, like me, have very few.

    • By Tracey (not verified) on 25 Jan 2020 - 08:54

      I totally understand these. It’s dehydration, right now I drink 8oz of water every hour (awake) and every time I go to the bathroom at night. These are my greatest problems in pregnancy “headaches/migraines and constipation” which caused hemorrhoids in my last pregnancy

      Hi doc, am pregnant with triplet, I lastly saw my menses on the 20 of August, and I have been going through several ultrasound now, but up still this moment they can feel the heartbeat of the children and tomorrow is my last chance to do another ultrasound and if there is no heartbeat they will remove the babies, and am so scared because I had a miss abortion in 2017 because of heartbeat at 12week. Now am thinking this may occur the same.

    • By Bebe (not verified) on 7 Nov 2019 - 16:30

    • By Kara (not verified) on 7 May 2019 - 15:39

      Hey I'm 12 weeks 4 days my last appointment was when I was 11 weeks the dr didnt try to get a heartbeat he said it's still to early but I also found out that I had Gonorrhea I was treated but the dr said it could cause miscarriage what I'm worried about is that I have had no symptoms of pregnancy sense my ultrasound at 9 weeks 4 days baby was healthy and very very very active with a heartbeat of 165. Is it possible that the baby isn't there anymore sense all my symptoms are gone the only symptoms I had was breast soreness food cravings and weird dreams.. my next appointment is when I'm 15 weeks what should I expect?

      I am 12 weeks pregnant and have severe pain in my shoulder which ends till my hand and fingers. I can't have pain killers and exercises are not working. Can go through TENS and ultrasonic therapy.

    • By Courtney (not verified) on 17 Dec 2018 - 20:03

      Hi. I'm 12 weeks pregnant and I am very scared. This is my first pregnancy and I suffer from Pcos so my thoughts are always all over the place. While I am VERY happy, ppl in my family seem to think I'm not. And my husband keeps telling me to "push pass the tiredness" I work overnight and I have a issue sleeping during the day so I'm always drained. I feel unmotivated and uncomfortable. Idk what to do. I have a therapist who gives me great advice but some things still bother me and I get emotional and sometimes aggressive. I don't want my baby to be stressed as I fear for miscarriage.

    • By Midwife @Tommys on 20 Dec 2018 - 14:46

      Hi Courtney, Excessive fatigue is a very common symptom in early pregnancy and it is more likely to be the pregnancy than the PCOS that is responsible for your symptoms. For most women this does gradually resolve after 12 weeks and women report having much more energy in the second trimester. All we can suggest is that you eat a balanced and healthy diet and if possible, try to get out each day either to exercise or just to get some fresh air. Working night shifts is hard at the best of times, but I can understand in pregnancy it is especially difficult. Try talking to your line manager about changing your shift pattern if the fatigue continues after Christmas. With best wishes from Tommy's midwives

    • By Rachel (not verified) on 12 Dec 2018 - 20:21

      The dentist began a root canal treatment prior to me being pregnant. I am now 12 weeks pregnant and haven’t had the root canal finished yet as the dentist said I could leave it while I’m pregnant as long as it’s not sore. I have very slight pain tonight. How safe would it be to have a root canal? Are local anaesthetics ok to have? Thank you!

    • By Midwife @Tommys on 14 Dec 2018 - 15:26

      Hi Rachel,
      Most dental treatment is avoided in pregnancy, especially x-rays. However local anaesthetic is usually thought to be safe in pregnancy, therefore if you are having pain then I would advise for you to speak with your dentist to discuss having treatment.
      Best wishes

    • By Bella (not verified) on 4 Dec 2018 - 15:51

      Hi everyone,
      I am 11 weeks pregnant. The physical symptoms are easing off, but my mental health is deteriorating. I have Hx of PTSD, Depeession and emotionally unstable personality disorder. I feel like I am becoming disillusioned and cannot trust my judgement. One day I want the baby, the next I don’t. It was a planned pregnancy and I am in a stable good relationship, but it seems I am doubting every decision I make at the moment. I feel I am splitting and feel I am almost psychotic at times. I am very healthy physically, I do yoga and meditation, sleep and eat well, but my emotions are driving me crazy. I have a GP app. but fear they will only give me meds, which I won’t take. My midwife has been amazing and referred me to Obs consultant urgently, but in the meantime..... I am struggling. My friends and family live far away and I feel quite isolated. My psychiatric problems don’t respond to standard antidepressants and I will not be convinced to take antipsychotics or mood stabilisers die to risk to the baby. Has anyone got any tips how to manage unstable emotions! When I am not pregnant I am well and meditation and yoga help me keep on top of it, but I fear the hormones are playing havoc with my brain. Thank you

    • By Midwife @Tommys on 5 Dec 2018 - 10:44

      Hi Bella
      Congratulations on your pregnancy. And well done for asking for advice. If you want to call us and have a chat(0800 0147800), we are here Mon to Fri, 9 am to 5pm. I do suggest that either your midwife or your GP refer you to a perinatal mental health specialist midwife (if this has no already happened) as they will be able to offer you more support via extra appointments, longer appointment slots and access to other practitioners on the perinatal mental health team (such as the psychiatric doctors etc) who can help you to weigh up your options. Your own GP will also be able to refer you to local talking therapies, if this is something that you feel would be useful for you at this time. It sounds as if you are incredibly self aware and doing all that you can to keep yourself fit and well, mentally and physically. Well done!
      And make sure that you talk to your partner, close family and friends about how you are feeling. Even if they do not live nearby, a listening ear and advice and support from those who love you, will always mean such a lot.
      Please do get in touch with us soon :) Tommy's Midwife

    • By Hellen (not verified) on 15 Sep 2018 - 13:51 recently 12 wks pregnancy. I have had a series of vomitting and morning sickness but now im starting to feel a little bit better. So i have started to feel my baby's movements is is realy and normal? or just not yet. Thank you

    • By Midwife @Tommys on 17 Sep 2018 - 11:03

      Hi Hellen,
      It is unlikely that what you feel is baby movements but you don't have too long to wait. Many women start to feel some movements around 18 weeks and some (mostly women who have had a previous baby) will start to feel movements around 16-17 weeks. Take care.

    • By Carol (not verified) on 21 Jun 2018 - 05:06

      I'm experiencing an itchiness on my biginah there is a white discharge coming out by him offensive,i bought viginal cream but its nt working, and I'm 8weeks pregnant.

    • By Midwife @Tommys on 22 Jun 2018 - 15:14

      Hi Carol,
      If you are having itchiness and white discharge then this could be thrush, if the cream is not helping then do see your GP for review.
      Best wishes

      Hi! I'm almost twelve weeks pregnant and I have had series of vomiting but thank God it has stopped around 10 weeks this is my first pregnancy and I'm very excited!!!the only thing I'm really scared of is miscarriage!!!oh lord I dread it!!!

    • By Mandy h (not verified) on 29 May 2018 - 10:47

      Hello I'm roughly 12 weeks pregnant. I had a scan at 6 weeks which showed heartbeat. I'm just extremely worried because my last pregnancy when I went for a second scan at 12 weeks the baby was no longer alive which came as a total shock due to no bleeding etc.
      How can I tell if everything's ok and my baby's still alive? I don't suffer many pregnancy symptoms except sore boobs now and then but they've eased off now

    • By Midwife @Tommys on 1 Jun 2018 - 09:46

      Dear Mandy,
      I am so sorry to hear that you have experienced a miscarriage, and it is completely understandable that you are feeling so anxious in this pregnancy. Please be reassured that it is very normal for pregnancy symptoms to ease towards the end of the first trimester. If you continue to feel particularly anxious the n do contact your GP or midwife for support. I really hope that your upcoming scan all goes well.
      Best wishes
      Tommy's midwife

    • By TesniBora (not verified) on 24 Dec 2018 - 07:08

      Dear Mandy I was sorry to hear about your previous miscarriage from the pregnancy prior to the one you mentioned in May. Thoughts and wishes of a good and healthy pregnancy with the May mentioned unborn baby and good luck to you and your family!

    • By Husna (not verified) on 27 Apr 2018 - 16:50

      Pls I need 7 weeks pregnant .but am feeling the movement of the possible is that?

    • By Midwife @Tommys on 30 Apr 2018 - 09:39

      Hi Husna, The feeling that you have will not be baby movements as at 7 weeks gestation the baby is very small and the uterus is protected well within the pelvis. If you think that you could be further on in your pregnancy, you should see your doctor for review.

    • By Roma (not verified) on 5 Apr 2018 - 06:07

      Hello I have not been offered a dating scan till 14/15 weeks I haven’t even seen a midwife is this normal or should I go and see a midwife before this appointment. I’m getting really short of breath on exertion and I’m normally fit and healthy and exercise regularly I haven’t been so much in the past ew weeks.

    • By Midwife @Tommys on 6 Apr 2018 - 12:14

      Hi Roma,
      The initial dating scan should be done before 13+6 weeks of pregnancy, particularly if you have chosen for the combined screening. You should see a midwife before this scan, to go through your medical and pregnancy history and discuss screening options available, this ideally should be done by the time you are 10 weeks pregnant. If you have a way of arranging a midwife appointment then do, otherwise contact your GP and they can refer you.
      Best wishes, Tommy's midwives

    • By Mandy (not verified) on 27 Feb 2018 - 06:49

      Hi I m just wondering I m 10 weeks pregnant I m getting very sick could eat anything always throwing out everything could you pls tell me what can I do or when it’s goona stop I even feel very weak can not even stand nothing digest

    • By Midwife @Tommys on 28 Feb 2018 - 10:12

      Hi Mandy
      Congratulations on your pregnancy. But i am sorry to hear that you are suffering with nausea and vomiting. Things should start to ease by 12 weeks, but if you are really struggling to keep anything at all down including water, you may need to go to be seen by your maternity triage. If you have Hyperemesis you may need an infusion of IV fluids to re-hydrate you. Please see the link below about nausea and vomiting in pregnancy for some handy tips in case there are some that you haven't tried yet. All the best, Sophie Tommy's Midwife.

    • By Cleo (not verified) on 31 Mar 2018 - 10:37

      You could try biscuits like Marie or dry stuff like crackers,make sure to always keep some in your hand bag always

    • By PregnancySantander on 5 Sep 2017 - 12:29

      I don't feel like my pregnancy is real, I have my first ultrasound in 9 days and I am so nervous and scared, I know these feelings are normal but cant help thinking of all the things that can go wrong. Only symptoms I have had are sore breasts and nausea and sickness.

    • By Midwife @Tommys on 5 Sep 2017 - 14:58

      thank you for posting because it is so good for other Mums to be to see that we all worry about similar things. It is really normal to worry about things going wrong and if you don't have too many symptoms then associating this with a failing pregnancy. The symptoms you do have though are normal at this stage of pregnancy and there is nothing to suggest from your post that you have anything symptom wise to worry about.
      I hope you can try and fill the next 9 days with distractions so it doesn't feel like an eternity.
      Please call if you feel like a chat. Wishing you a healthy pregnancy

    • By Siobhan (not verified) on 23 May 2017 - 10:21

      Hi, sorry me again. I'm 12 weeks plus 4 days, I had a scan on Friday, all was well. I have had two miscarriages in past year (one at 12 weeks and one at 7 weeks). Yesterday I had brown streaks in my discharge but nothing overnight or since. I called the non-urgent midwife number on my notes and the midwife answered on labour ward (?!). She was very nice but said I needed to call my GP who can then refer me to EPU at my hospital. I have been offered an appointment with the GP today at 4:20pm. I thought they'd just make a referral over the phone so I was just wondering what might happen at the GP appt? What can they do to offer reassurance/assess whether miscarriage likely? Or is it just part of procedure to refer me to the EPU? Thanks very much, I'm just trying to make myself aware of what to expect, my husband is away so I'll be going alone. Thanks, Siobhan

    • By Midwife @Tommys on 23 May 2017 - 10:43

      Hi again Sibohan
      Your GP will do the referral to the EPU at your appointment- sometimes by phone,fax,email for ASAP for you. Most EPU's require a GP referral, very few offer "self referrals".
      Please do take good care of yourself- perhaps take a friend or relative along for support if you are concerned and your husband is away.
      Take care

    • By Siobhan (not verified) on 23 May 2017 - 07:50

      Hi, I was 12 weeks on Friday 19th and we had our scan that day too. It was amazing to see baby alive and well. I have had two miscarriages within the last year. Yesterday (22nd) afternoon when I wiped there were a couple of brown streaks within my discharge. I have been really really worried but I've had nothing else since then. I feel fine. Do you think I need to contact my midwife or take any action? The thought of another miscarriage is terrifying. Thank you

    • By Midwife @Tommys on 23 May 2017 - 09:16

      Hi Siobhan, congratulations of your pregnancy
      Brown discharge is evidence of old, not new. If you have no abdominal pain and no red or pink bleeding before or after this, then it is likely to be ok. If you are concerned about it though understandably, due to your history, then you can always be seen in your local early pregnancy assessment unit.
      Any fresh red or pink bleeding or abdominal pain at any gestation should be investigated by a midwife/obstetric doctor/gp.
      Please take good care of yourself

    • By Siobhan (not verified) on 23 May 2017 - 10:06

      Thank you. I'm currently awaiting a call back from my GP. Much appreciate your reassurance, fingers crossed all will be well. Kind regards, Siobhan
