12 Weeks Pregnant: Symptoms, Baby Development & Care Tips

12 weeks pregnant marks a wonderful milestone because you are reaching the end of your first trimester and completing around three months of pregnancy. That’s really exciting! By now, many of the hormonal changes that caused early pregnancy symptoms, such as nausea and fatigue, may begin to ease for some women, but it’s important to remember that every pregnancy is different. Also, if you had been keeping this happy news under wraps, it’s about time to spill the beans. Many parents choose this stage, as the risk of miscarriage has generally decreased after the first trimester. While your baby bump may still be subtle, your baby is growing rapidly, and important organs have developed significantly, making this a reassuring and memorable phase of pregnancy.

Your Baby’s Growth During Pregnancy – Week 12

Adding to the development of the baby’s organs, your baby’s sex organs may already be showing externally or may show any minute depending on the hormonal activity taking place.

Per the American Pregnancy Association, your baby will start acting on reflexes such as sucking. Your baby’s kidneys will also be functional as they can now start producing urine (1). Its urinary and digestive systems are also fully functioning. What was previously just a bed for fingers may also manifest as fingernails at the end of 12th week. Thus, the fetus will have toes, fingers and nails by now. The fetus may also start to open and close its hands and mouth.

What Is the Baby’s Size?

After finding out about the growth of your baby, it’s only natural that you are eager to know about the 12 weeks pregnant baby size.

By this time, your baby would be the size of an apricot or a plum. This means that it has grown around 3 to 4 inches (5 to 6 cm) from a mere 2 inches at the end of the 12th week (2). It is also worth knowing that your baby weighs around 28-29 grams or just a mere ounce. More importantly, your baby’s body has developed a digestive system and the bone marrow has already started producing white blood cells.

Common Body Changes

According to Pregnancy, Birth, and Baby, by week 12 of pregnancy, your uterus will be shifted slightly so there is no pressure on the bladder like the early weeks of pregnancy. You may also feel less tired comparatively and can get back to doing activities that you previously enjoyed but couldn’t do because of fatigue and tiredness (3). Nausea and vomiting will also start to subside, though may not go fully. Other common body changes during pregnancy include a bit of weight gain, maybe around 500 grams or a kilo.

More importantly, your uterus is steadily growing, and your doctor may already be able to feel it in your lower abdomen. Otherwise, you will continue to get curves. Though you may be showing only a hint of a bump, your clothes will most definitely feel tight.

12 Week Pregnant Symptoms

There’s a lot happening in the body at this time and you’ll find some symptoms fading out and some new or continuing symptoms of pregnancy at the 12th week. Here’s a quick review of twelve-week pregnancy symptoms (4).

• Melasma or an increase in the pigmentation of the skin. This is caused due to hormonal changes that temporarily increase the melanin in the skin. Alternatively, you could see your skin looking flushed, plumper, and smoother. This is called “pregnancy glow.” (4)
• Breasts starting to feel sore as they prepare to start producing milk.
• Darkening of the areolas around the nipples due to increased pigmentation.

Besides that, let’s revisit some of the symptoms of week 12 pregnancy which you may already have grown accustomed to by now.

• Vaginal discharge: This is usually experienced to protect the vagina against infection.
• Headaches: Many women experience headaches due to the lower blood sugar levels in the blood
• Spotting: A special mention to this because not every instance of spotting means that you have miscarried. Don’t forget to contact your doctor regardless.
• Fatigue: Bouts of dizziness and fatigue can happen suddenly as the blood gets diverted to the baby (5).

Belly at 12 Weeks of Pregnancy

Are you wondering what is the 12-week pregnancy belly size? There should be some accelerated growth in this department, as you should be sporting a bump by the 12th week. Even if it’s not entirely visible, your body will certainly feel curvier and fit snugly with most of the clothes you own.

Even if there is no bump showing yet, your underbelly may certainly feel heavier than it used to before you got pregnant.

12 Weeks Pregnant Ultrasound

In your 12-week pregnancy scan, you will see that your baby has all the correct organs in place, meaning that it’s only a matter of maturation from this point onward. Along with continuing to grow steadily bigger, your baby’s tissues will also grow and mature.

According to the Cleveland Clinic, at 12 weeks of pregnancy, your provider can comfortably listen to the fetal heart using a Doppler ultrasound (6).

The baby’s brain has developed and will continue to develop in the coming weeks. Your baby can now curl their toes and make some fingers movements, such as opening and closing. Above all, your baby has now grown reflexes so far as to be reacting to your touch or belly poking which of course is visible only in a twelve weeks pregnant ultrasound.

What to Eat

This question may have haunted you most of your pregnancy, and for many, the question of 12th week pregnancy food will continue to be bothersome. Nevertheless, your target should be to form a balanced diet, regardless of how averse you may be to food right now. Below is a suggestion regarding a 12-week pregnancy diet that can help you.

• Pick fruits and green leafy vegetables which contain vitamins and minerals.
• Avoid junk food and choose snacks like nuts, yogurt and sunflower seeds. Nutritious and satisfying, they ensure you stay full for longer.
• Don’t forget to add quite a bit of lean protein, most commonly chicken and fish, as it helps the baby’s bones and muscles develop.
• Eat complex carbohydrates as they as essential for foetal development.
• Eat foods with more fibre as they help relieve constipation.
• Try and eat for two, but do not overeat so that there is optimum weight-gain.

Tips & Care

Completing the first trimester of your pregnancy, which may have been painful and difficult for many, nonetheless, reminds you that there is no turning back from this moment on. This means that now it is your responsibility to keep both yourself and your baby healthy and protected. Your lifestyle choices will most certainly reflect on your little baby, which is why it’s important that you take care of yourself above all.

Dos

Below are listed some pointers that should be done during the 12th week of pregnancy.

• Eat frequently to keep your blood sugar in check. However, be careful not to overeat.
• Take care of oral health, especially since your hormones may contribute to gum bleeding.
• Continue moderate exercises, like walking, swimming, prenatal yoga, and stationary bicycling. Just make sure not ot overexert yourself (7).

Don’ts

Below are listed some pointers that should not be done at any point of your pregnancy (8).

• Don’t smoke as it can increase the chances of respiratory problems for the baby significantly.
• Don’t drink alcohol as it affects the growth of the brain and the cells of the spinal cord.
• Don’t try any extreme slimming options such as starving yourself as it could affect the baby adversely.
• Avoid living in poor conditions such as lack of ventilation, or in places which are too hot or too cold
• Avoid saunas or hot tubs as the body is unable to sweat properly because of an increased blood supply and hormones. This means that the body is unable to lose heat effectively and affects the baby as the body temperature rises.

What You Need to Shop for

Pregnancy shopping at the end of the first trimester is generally not that different from the last couple of months. However, it’s important to invest in good shoes because uncomfortable shoes may add to headaches, interfere with the body’s balance or even contribute to leg cramps and swelling of your feet.

You can go ahead and invest in good parenting books, comfortable stretchy bras, some may even opt for nursing bras as they will come in handy very soon. You may also look into investing in a good pair of maternity jeans if you wish to continue wearing jeans but are worried about the fitting of your regular ones. Then there are lovely printed maternity tunics with pockets from Bella Mama. Stock up on healthy food and snacks. Invest in maternity clothes. Don’t forget to buy good oral health-care products. Invest in good lotions and moisturisers. Do consult your doctor and stock up on vitamins that will help both you and your baby.

FAQs

1. Is it normal to experience nosebleeds at 12 weeks pregnant?

Yes, nosebleeds can occur around this time due to increased blood volume and hormonal changes that make blood vessels in the nose more sensitive. Staying hydrated and using a humidifier can help alleviate this symptom.

2. Can pregnancy affect my gums or dental health at this stage?

Yes, pregnancy hormones can increase blood flow to the gums, making them more sensitive and prone to swelling or bleeding, a condition known as “pregnancy gingivitis.” Regular dental hygiene and visits to the dentist can help manage these symptoms.

3. Why do I feel like I’m “showing” more in the evenings?

It’s common to feel like your belly is more prominent by evening. This is often due to bloating from hormonal changes and water retention rather than the baby bump itself. It usually subsides by the morning and becomes more noticeable as your baby grows.

How many months is 12 weeks of pregnancy?

Being 12 weeks pregnant is generally considered to be about three months into pregnancy and marks the end of the first trimester. According to the Cleveland Clinic, each trimester is about 13 weeks long, or 3 months (6). This stage is an important milestone, as your baby’s major organs have formed and many women begin entering the second trimester soon afterwards.

By the 12th week of pregnancy, you’re well into your second month of pregnancy, and the symptoms like headaches and dizziness may make regular work a little tedious. However, many may start experiencing fewer bouts of morning sickness. The good news is that this is probably the last tough week, after which many of these symptoms are likely to disappear.
