12 Weeks Pregnant—What To Expect Plus Caring For Yourself & Baby

12 Weeks Pregnant

Congratulations on reaching 12 weeks of pregnancy! You’re now in the last week of your first trimester and about to enter your second trimester, and your baby has already grown so much.

This article will explore what you can expect during this exciting time and provide tips to help you make the most of your pregnancy journey. 

So, sit back, relax, and let’s delve into the world of being 12 weeks pregnant!

Your baby at 12 weeks pregnant

In just a couple of months, your little one has gone from a tiny cluster of cells to a very tiny human being. 

Let’s look at what’s happening with your baby’s development at 12 weeks.

How big is my baby at 12 weeks pregnant?

By pregnancy week 12, your baby is about the size of a plum – around 2.1 inches (5.4cm) from crown to rump and weighing about half an ounce (14 grams). Your baby is fully formed, though still very small. 

All major organs and systems are in place. Your baby’s intestines move out of the umbilical cord and back into the abdomen.

Their eyes are now positioned closer together, and their ears move to their final position. 

Your baby can now open and close its fist and even make facial expressions! 

Their vocal cords also form to move their mouth and tongue.

Your baby’s brain at 12 weeks pregnant

Your baby’s brain is developing incredibly fast. 

Millions of neurons (brain cells) are forming every day. These neurons will continue to form connections throughout your baby’s life, but at the moment, they are laying the foundation for all future development and learning.

At 12 weeks, your baby’s digestive system is also starting to work. They can now swallow amniotic fluid, which helps their intestines develop. 

Their liver is also starting to produce bile, which is an essential component of the digestive process.

Finally, at this stage, your baby’s movements can be detected by ultrasound, although you may not feel them yet. Your little one will likely be very active, frequently moving around and changing positions.

While your baby is still small, they are growing rapidly, bringing new daily developments. 

At 12 weeks pregnant, caring for yourself and your little one is crucial, and getting ready for the exciting journey ahead!

Pregnancy symptoms at 12 weeks pregnant

At 12 weeks pregnant, you’re almost at the end of the first trimester! While you may start feeling better soon, some symptoms may persist. 

Here are some common pregnancy symptoms you may experience at 12 weeks.

1. Morning sickness

While morning sickness typically peaks around week 9, some pregnant women may experience nausea and vomiting until week 12. This is due to the hormone changes in your body.

2. Fatigue

Your body is working hard to create a new life, so it’s no surprise that you may feel more tired than usual. Try to take it easy and rest when you can.

3. Mood swings

Hormonal changes can also cause mood swings, making you happy and teary-eyed. Remember that this is normal, and try to take care of yourself by eating well, getting enough sleep, and practicing self-care.

4. Frequent urination

As your uterus expands, it puts pressure on your bladder, making you feel like you need to urinate more often.

5. Breast changes

Due to hormonal changes, your breasts may be sore, tender, or feel fuller than usual.

6. Constipation

Hormonal changes can also slow down your digestive system, causing constipation. 

Try to eat a high-fiber diet and drink plenty of water.

While these symptoms can be unpleasant, they’re all normal and a sign that your body is working hard to create a new life. 

Don’t hesitate to talk to your healthcare provider if you’re struggling with these symptoms. They can offer tips and advice on managing these symptoms and ensuring you and your baby are healthy. 

Remember to take care of yourself, listen to your body, and reach out for the support you need.

Self-care at 12 Weeks Pregnant

Self-care is crucial during pregnancy. Taking care of yourself physically and emotionally is essential, especially when symptoms such as fatigue, mood swings, and digestive issues get in the way.

Here are some self-care tips for you to consider at 12 weeks pregnant.

1. Eat well

A healthy diet is essential during pregnancy. 

Ensure you eat a balanced diet with plenty of fruits, vegetables, whole grains, and lean protein. Avoid high-sugar or high-fat foods; drink plenty of water to stay hydrated.

2. Stay active

Regular exercise can help you feel better physically and emotionally. Talk to your healthcare provider about what exercise is best for you. Walking, swimming, and prenatal yoga are all great options.

In addition, try exercises that strengthen your pelvic floor muscles, such as Kegel exercises. These muscles, when trained well, promote faster post-birth recovery and support the bladder and uterus throughout the rest of your pregnancy journey.

3. Rest

Your body is working hard to create a new life, so it’s essential to rest when you need it. Try to get enough sleep each night and take naps when you can.

4. Skincare

Pregnancy hormones can cause changes in your skin, such as acne or dryness. Use gentle, pregnancy-safe skincare products, and wear sunscreen to protect your skin from the sun’s harmful rays.

5. Practice relaxation techniques

Stress can have adverse effects on your health and your baby’s development. Consider practicing relaxation techniques such as deep breathing, meditation, or prenatal yoga.

6. Connect with your partner or close loved ones

Pregnancy can be an emotional time, and it’s essential to have a support system. Spend time connecting with your partner and openly communicate your feelings and concerns.

7. Treat yourself

Take time to do things that make you feel good! Whether getting a prenatal massage, a warm bath, or reading a good book, take time for yourself.

Taking care of yourself during pregnancy is essential for your health and your baby’s development. 

Remember to eat well, exercise, rest, care for your skin, practice relaxation techniques, connect with those close to you and pamper yourself. 

By prioritizing self-care, you give yourself and your baby the best chance for a healthy pregnancy and delivery.

FAQs at 12 Weeks Pregnant

It’s normal to have many questions during this pivotal stage of your pregnancy. We’ve answered some of the most common ones below.

What not to do at 12 weeks pregnant?

Pregnancy is an exciting time, but it’s also when you must take extra care of yourself and your growing baby. That means avoiding some things you enjoyed when you weren’t pregnant. Here are some things you really should avoid at 12 weeks pregnant.

  • Smoking
  • Alcohol
  • Raw or undercooked food
  • Certain medications
  • Hot tubs and saunas
  • Strenuous exercise:
  • Excessive stress

Caring for yourself and avoiding these things gives you and your baby the best chance for a healthy pregnancy and delivery.

Can I lay on my back at 12 weeks pregnant?

Even though lying on your back is considered safe during the first trimester, it’s essential to avoid it as your pregnancy progresses. 

When you lie on your back, the weight of your uterus and growing baby can put pressure on a major vein called the inferior vena cava. This can reduce blood flow to your baby and cause dizziness, shortness of breath, or nausea.

So, start practicing sleeping on your side (which is recommended for the remainder of your pregnancy.)

Sleeping on your left side is generally considered best, as it improves blood flow to the placenta and your growing baby. 

If you wake up on your back during the night, don’t worry – simply turn onto your side as soon as possible.

Where is the baby located at 12 weeks?

By 12 weeks pregnant, your uterus has grown significantly and is now about the size of a grapefruit. 

Your baby is positioned inside your uterus, in the amniotic sac, filled with amniotic fluid surrounding and protecting your baby. 

They are fully formed, and their growth and development will continue throughout your pregnancy. 

Enjoy this exciting time as you watch your little one grow and prepare for their arrival!

What to expect at a 12-week ultrasound?

A 12-week ultrasound, a dating scan, is an important milestone in your pregnancy. This ultrasound is used to confirm your due date, check your baby’s development, and detect potential issues. 

The first ultrasound usually takes place at around 7 to 8 weeks, so this may not be your first. However, sometimes the first ultrasound happens at 12 weeks.

Here’s what you can expect during a 12-week ultrasound.

  1. Preparation: Before the ultrasound, you’ll be asked to drink water to fill your bladder, which helps improve the visibility of your uterus and baby on the ultrasound screen.
  2. Procedure: During the ultrasound, a technician will apply gel to your abdomen and use a handheld device called a transducer to obtain images of your uterus and baby. The technician will measure the length of your baby from crown to rump to confirm your due date and check for any abnormalities.
  3. Images: You’ll see images of your baby on the ultrasound screen, including its head, body, limbs, and organs. This is an excellent opportunity to see your baby and its development for the first time.
  4. Diagnosis: The technician will check for potential issues, such as baby development abnormalities or multiple pregnancies. If any issues are detected, your healthcare provider will discuss them with you and arrange follow-up testing or care.
  5. Duration: The ultrasound usually takes around 30 minutes but may take longer if any issues or additional measurements are needed.

Why are 12 weeks considered safe?

Pregnancy is an exciting time, but it’s also when you must take extra care of yourself and your growing baby. 

Many women wonder why 12 weeks pregnant is considered a safe time in pregnancy. Here are some reasons:

Major organs are formed: By 12 weeks, your baby’s vital organs have formed. This means the risk of congenital disabilities and other abnormalities is significantly reduced.

Placenta takes over: By 12 weeks, the placenta has taken over the job of nourishing your baby. This means that the risk of miscarriage is significantly reduced.

Nausea and vomiting decrease: Morning sickness and some other early pregnancy symptoms typically peak around week nine and start to decrease by week 12. This means that you may start feeling better and have more energy.

Reduced risk of complications: The risk of certain pregnancy complications, such as ectopic pregnancy and gestational diabetes, is reduced after 12 weeks.

Increased prenatal care: By 12 weeks, you have likely had several prenatal appointments, and your healthcare provider has been monitoring your pregnancy closely. This means that any potential issues can be detected early and treated promptly.

12 weeks pregnant is considered a safe time in pregnancy because the major organs are formed, the placenta has taken over, nausea and vomiting decrease, the risk of complications is reduced, and prenatal care is increased.

However, it’s still important to continue caring for yourself and your growing baby throughout pregnancy. If you have any concerns or questions, talk to your healthcare provider. 

Caring for yourself and your baby gives you the best chance for a healthy pregnancy and delivery.

When will I see my baby bump?

It may still be a while before your pregnant belly starts to show. By week 12 you may notice some healthy weight gain, but your baby bump won’t begin to show until sometime between 16 and 20 weeks pregnant. 

Consider also that baby bump appearance can vary based on factors such as whether this is a first or subsequent pregnancy or your pre-pregnancy body weight.


The end of your first trimester is an important milestone in your pregnancy journey. 

Congratulations on making it this far. Remember to prioritize self-care and avoid behaviors and habits that may risk your baby’s health. 

Continue to rest, eat well, and enjoy the miraculous journey you’re on!
