12th week of pregnancy – All about your baby, body and tips for you

12th Week of Pregnancy (Week 12)

Congratulations, you are almost at the end of your first trimester. A lot is happening in week 12 – both for your baby and for you.

This week marks the transition to a more stable phase of pregnancy. At the latest after your check-up and the reassurance that everything is fine, you’ll probably want to share your news. Are you considering having a first trimester screening? Speak to your doctor or midwife about it.

Your baby continues to grow rapidly and most organs have already developed. For you, too, things often become easier in week 12, as many women report that symptoms such as nausea start to subside.

Week 12 at a glance

Your baby:

In week 12, your baby is about 5 cm long and weighs around 14 grams – about as much as a raspberry.
Fingers and toes are fully formed in week 12 and start to move.
The face looks more and more human, eyes and ears are in position.
Organs such as the liver and kidneys are already functioning, and the nervous system continues to develop.

Your body:

In week 12, your uterus is about the size of a grapefruit and begins to move from the pelvis into the abdominal cavity.
The risk of miscarriage drops significantly.
You may already notice small changes to your belly in week 12.
Your hormones are gradually balancing out, often leading to an improvement in your mood.

Good to know about baby and mum:

Your baby starts to drink amniotic fluid and "practise" in it.
A balanced diet rich in folic acid, iron, and calcium remains essential in week 12.
Drink plenty of water and keep active in moderation to support your circulation.

Baby's development in week 12:

In week 12, your baby is a good 5 cm long and has reached the size of a plum. With a bit of luck, you might be able to spot your little one's button nose on the ultrasound image.

Your baby continues to develop into a little person. It even begins to move its hand to its face and can suck its thumb, as the sucking reflex is developing. Fingernails and toenails are also starting to grow. The stomach is now able to absorb substances.

To practise breathing and later feeding, your baby now swallows a little amniotic fluid from time to time. At this stage of pregnancy, however, it usually spits it out again.

In addition, your little one is constantly busy doing somersaults in week 12. There is still plenty of space and your baby makes good use of it. But don’t worry if you can’t feel any of this yet. It may be a few more weeks before you do.

Your body in the 12th week of pregnancy:

Have you suffered from nausea in the past weeks? With a bit of luck, it will be significantly better this week. That’s because many women have now got used to the pregnancy hormone HCG. Please don’t worry if your nausea continues beyond the first trimester. Every pregnancy is different.

One thing you can rely on now, though, is that the risk of miscarriage decreases at the end of the 12th week of pregnancy.

Tips for the 12th week of pregnancy

Are you currently feeling particularly tired? That can be quite normal, but for many pregnant women, it is linked to an iron deficiency. This is regularly checked by your gynaecologist. Normally, the iron requirement for adult women is 15 milligrams per day. However, for pregnant women, 30 milligrams per day is recommended.

Many foods that are very rich in iron, such as black pudding, are off-limits for you during pregnancy. You can get an extra portion of iron from, for example, pulses like lentils and beans, green leafy vegetables such as lamb’s lettuce and spinach, or herbs like parsley or cress. However, many pregnant women are prescribed iron as a dietary supplement.

Don’t forget your prenatal check-ups:

The 12th week of pregnancy is a good time to schedule another check-up with your gynaecologist. The nuchal translucency scan, in particular, can be carried out upon request to check your baby's health. Talk to your doctor about the next steps and possible protective measures to optimally support yourself and your child.

Healthy nutrition for mother and child:

Make sure to get enough vitamin C and other nutrients that are important for building your child’s body structures. Avoid raw milk products, ready-made salads, and raw meat to minimise the risk of infection. You are doing a lot of work right now – support yourself with fresh, nutrient-rich foods.

Moderate exercise and relaxation:

Light activities such as pregnancy yoga or walks promote your blood circulation and strengthen your muscles. This can help to alleviate pregnancy complaints such as back pain or stomach pressure. At the same time, relaxation techniques like meditation or breathing exercises help to reduce stress and deepen your connection with your baby.

Planning and preparation:

Now that the critical phase is over, you will surely start thinking about your first purchases. Whether it’s a pram or clothing – planning brings joy and gives you the feeling of having everything under control. Discuss your wishes with your partner or your family and look forward to the little miracle together.

Take care of yourself:

Your body changes every day. Take time for yourself – whether it’s a relaxing bath, a gentle massage, or reading a good book. Self-care is important to maintain your energy and to enjoy the joy of your pregnancy.

Frequently Asked Questions about Week 12 of Pregnancy

Is it normal for the nausea to suddenly disappear?

Yes, the disappearance of nausea is typical, as you are adjusting to the hormonal changes. Many pregnant women experience a significant relief from symptoms around the end of the third month of pregnancy. The placenta now takes over the nourishment of the baby, and the yolk sac becomes less important. Appetite and energy return – a phase full of new joy for the world that you share with your baby.

From when is the bump visible?

The belly usually begins to visibly grow around the third month of pregnancy. Your baby is now about 5 cm long and the diameter of its head is increasing. The mother's muscles and body structures loosen to make room for the baby. The development of the placenta is complete and provides protection. Every pregnancy is different, so if you have any concerns, speak to your gynaecologist.

What should I pay attention to in my diet?

Avoid raw milk products, ready-made salads, and raw meat/fish – protective measures that benefit both your child and your stomach. Your body now especially needs vitamin C, iron, folic acid, and proteins for the work of building your baby’s important structures. Fresh fruit and vegetables are a good choice to provide your baby with the best possible care.

How can I relieve pregnancy discomforts?

Light exercises strengthen the muscles and promote blood circulation, which can alleviate complaints such as stomach pressure. Moving your hands and feet supports circulation. Relaxing in a warm, but not hot, bath helps to loosen the body. Your employer should pay attention to physical strain as part of the protective measures.

Is the risk of miscarriage still high at 12 weeks pregnant?

With the end of the third month of pregnancy, the risk of miscarriage drops significantly. The placenta is fully developed and takes over nourishment. Your baby is about 5 cm long, the head continues to form, and even the little button nose is visible. With each check-up and ultrasound, you gain reassurance and can share the joy of your baby's development with friends and family.
