12 weeks pregnant

What's happening this week...

baby 12 weeks pregnant ultrasound

Your baby

In this final week of your first trimester your baby’s heart will be beating at a pace of about 160 beats per minute, which is twice as fast as your own. This is because it can’t increase the amount of blood it pumps round, like we can, so it has to increase the number of times it beats.

Your baby’s arms and legs will have fully formed and lengthened and no doubt it will be trying out loads of different positions.

Your little one is now measures around 6cm, with wrists and elbows that bend. The baby’s sex is decided at the moment of conception but the genitals will be just starting to develop. You won’t be able to see whether your baby is a boy or girl at this stage though.


If you’re permanently tired but finding it hard to sleep, don’t despair, most women start perking up in the second trimester – not long to go!

You may notice that your skin is changing from the 12 weeks pregnant symptoms. Some women may find they have acne, or develop spots; others have said they find they have dry skin. This is likely to happen because of the levels of the progesterone hormone. The dry skin may be worse over your belly as your skin is stretched, so keep well moisturised.

What to think about

Most women have their first ultrasound scan around now.  After this initial ultrasound you may want to begin telling your family and friends, but you may feel anxious about telling your boss that you’re pregnant. Find out more about when to tell your employer.

Dating scans are only an estimate, only around 5 per cent of women give birth on their due date. Keep the date in mind but be prepared for an early or late arrival.

Screening tests are available in your first trimester to assess the risk of abnormalities such as Down’s syndrome. Speak to your doctor or midwife for further advice.

Check out our handy checklist to make sure you've ticked off everything you need for your precious new arrival.

Baby bumps!

Hello I'm not sure how much help I'll receive from this, I suffered a M/C last year, and this is my 1st pregnancy after it, I'm scared pooless for the lack of a better expression! Although I'm seriously worried and not sure what to do, I don't want to contact mw in the case of wasting their time! I'm 12+3 and I have sevear bowel issues! I've had a bad weekend of it, to say the least and I was worried about pip because of what I had to do and go through.. My belly has been the same size and getting bigger these last few weeks/months. I know it wasn't bloating because I made measures before this weekend to make sure, but having checked out my "bump " it's completely gone!! :'( and it's soft .. I don't know what to think or do! Is this normal or should I call up mw ?? Can someone please help!!! I'm really worried and I can't go through a mc again I really really really can't :'( !!!! I measured it on and off for the last few weeks, and I was 30 inches plus! Now I barley hit 28! :-/ ....

Hi guys! I only found out I am pregnant a couple weeks ago (im probably around 10 weeks) and I called my doctor yesterday to confirm and he said he will refer me to antenatal. Does anyone know roughly how long it will take for my first appointment with a midwife? Thanks!

Hi! I'm 11 weeks and 2 days

Hi! I'm 11 weeks and 2 days into my first pregnancy. I have spent the last 2 months being sick, feeling sick and off food, every day and all day. I'm feeling pretty down and nothing seems to make me feel excited. I'm finding it really hard to function at work and as nobody at work has been pregnant, I'm finding it hard to explain how this sickness thing feels. I'm not feeling excited about the baby as I'm feeling so rubbish. When i see other peoples children running around, I just feel sick. This is all feeling very alien to me. Do these feelings sound normal?


Hii im 11 weeks and 4 days ! still hasnt sunk in yet as first baby, so scary when you hear so many stories of miscarraige im struggling to get excited, getting terrible heartburn already anyone else having this? cant sleep and recently caught a bug ! i never get unwell so just shows how low your immune system goes! soo scaryyy !!! x

I had a bit of spotting early on so have had a few scans and last one was at 8weeks 4 days and everything was fine. No spotting since then.

4th C Section worries!!

Hi all, I am new to Bounty and am 11 weeks pregnant with my 4th baby who, although not exactly planned, we are extremely excited about!! My only concern is that I will be having my 4th c section with this baby and had a lot of scar tissue and adhesions with my last baby. I am really worried but the doctor seems to think everything will be fine. Has anyone else had 4 sections without problems??

Hi all, I'm 12 weeks today

Hi all, I'm 12 weeks today and not been feeling too bad at all to be honest. Had a little heart burn, tiredness and period pain style aches but otherwise it's been good. This is my first but my husband's 4th. As I'm diabetic the midwife has put me on insulin which is quite hard to get used to but bearable. Hopefully our baby isn't going to end up huge.

Hi, this is my first

Hi, this is my first pregnancy, im now 9 weeks, and have already had 2 scans, 1 at 6 weeks and 1 at 8 weeks 3 days, due to bleeding.

feeling so poorly

I am 11 weeks and feel so sick all of the time, its really getting me down now.... I have a three year old and feel so bad as have no energy for her at all, poor little thing has been so good and let me sleep in and plays so well along. I just am worried that when baby comes I still wont have energy for her... I hope my hubby can have first two weeks off after baby so he can help with her and baby. I feel guilty already.... Doctor has given me some sickness tablets but I feel bad to take them everyday, if I dont I am like a wet blanket...

Scan :-)

thought i was further gone then i was so was booked in for a scan and went and i was 9weeks and 5days. It was an amazing experience but have been asked to go back again at 12 weeks to have another scan to check measurements again. My lil baby was sat in an awkward position ,( sat on its bum) legs apart and one arm in the arm near their face. It was amazing how much detail we saw. Cant wait for the 12 week scan . wish everyone the best with their scans x
