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.

More importantly, 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. What was previously just a bed for fingers may also manifest as fingernails at the end of 12th week.

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.

What Is the Baby's Size?

By this time your baby would be the size of an apricot or a plum. This means that it has grown around 3-3.5 inches from a mere 2 inches at the end of the 12th week. 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

By this time, it should be a no-brainer that your body will again show some sort of a change at the end of your first trimester. The common body changes during pregnancy include a bit of weight gain, maybe around 500 grams or a kilo.

Symptoms of Pregnancy at Week 12

In a saga of rapidly developing baby and mommy bodies, read on to find out more about the symptoms of pregnancy at the 12th week.

  • 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.
  • 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 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.

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.

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.


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

  • 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.

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.
