12 weeks pregnant - what to expect

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

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 to expect

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’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.
