12 weeks pregnant - what's happening

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

12 weeks infographic.

What does my baby look like?

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.

Your symptoms - what's happening

Congratulations - you’ve made it through the gruelling first trimester. You’re a third of the way through and hopefully over the worst of the morning sickness and tiredness.

Noticed you’re drooling in your sleep?

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


Random, we know - but some women find they’re more prone to nosebleeds during pregnancy. Blame hormones. Again.

Actions to take

The dating scan

Around about now you’ll be offered an ultrasound scan - and your first chance to see a glimpse of the tiny life inside you! It’s known as the dating scan as the sonographer will be able to check whether your due date is accurate by measuring fetus size.

Ask to have 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 may offer free NHS classes, or you can find out about NCT (National Childbirth Trust) classes.

The NCT charges a fee for classes but they may be more local to you - which can be helpful if you want to meet up with other parents-to-be in your area.

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

Now is the time to start thinking about where you’d like to give birth – how exciting!

Your midwife may have explained the different options and the pros and cons of each during your booking appointment. The choices that you have will depend on where you live and whether you have any health complications. But remember, if you decide early on in your pregnancy where you would like to have your baby, you can always change your mind later.

Breakfast club

Breakfast is a prime time to get a variety of essential nutrients for you and your baby – including B vitamins, folate, calcium and vitamin C.

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, this could be a good time.

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.

    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

    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.

    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

    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.

    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

    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

    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
