We explain to you how your body develops at 21 weeks of pregnancy and how your baby is growing. Let us help you clarify all your doubts.

With 21 weeks of pregnancy, your baby’s primitive immune system is already developed and can fight off some infections. After birth, your milk will help strengthen your baby’s natural defenses. Here’s the essentials about the 21st week of pregnancy .

21 Weeks of Pregnancy

  • Age of pregnancy: 21 weeks ( 5th month of 2nd trimester )
  • Fetal age: 19 weeks
  • 21 Weeks of pregnancy are 147 days of pregnancy
  • Length of the fetus: 26.7 cm (measure from head to toe)
  • Fetal weight: 300 to 360 g (approximately)
  • Size : pear avocado

Week 21 – 1st day

Baby Development

Your baby is now measured from the head to the heel, since the legs are better developed. It weighs between 300 and 350 grams and has around 23 cm, the length and weight of a banana.

He also has fully developed eyebrows and eyelids. At the tips of the fingers there are already nails.

The baby’s heart rate gets louder and louder every day. Until a few weeks ago, your doctor needed a special device called Doppler to listen to you. Now all he needs is a stethoscope.

Week 21 – 2nd day

Your baby

Your baby is starting to sleep and waking up in different cycles. Ultrasound examinations show that unborn babies can snuggle in their favorite sleeping positions. They can put the chin on the chest, support the hands over the chin or even tilt the head back.

The bones of the inner ear are forming entirely now, and the nose is beginning to take shape.

The audition is more accurate, so loud sounds may scare you. The baby recognizes the mother’s voice even better, so talking to him strengthens the mother’s bond. The parent can and should participate in this conversation. And if you have already chosen the name for the baby, then start using it!

Week 21 – 3rd day

Soluttions

You probably felt your baby rolling, diving and kicking inside the belly. Now you can also feel a rhythmic beat. No, he’s not beating a song, he’s sobbing. This serves as training for the respiratory system (amniotic fluid enters the lungs and is soon expelled on expiration).

Most babies begin hiccups in the uterus, possibly due to an immature diaphragm that has spasms. There is nothing you can do to stop the hiccups, but there is no need for it either – they are not harmful either now or after it is born.

Week 21 – 4th day

Your Body

Some back pains, especially in the lower part, are very common during pregnancy, and could not be different. The expanding uterus is shifting its center of gravity. Meanwhile, the relaxation hormone is softening all joints and ligaments in the body, including the ligaments that hold the pelvic bones attached to your spine. This will allow the pelvis to expand to accommodate the baby’s head in the correct position.

It is very difficult, especially in the third trimester, to find a comfortable sleeping position during pregnancy . Try to stand on your side with a pillow between your knees so the lumbar region has a support.

Week 21 – 5th day

Your Health

What is a good diet during pregnancy? First of all, do not make arrangements! Now is not the time to starve. It is also not time to lose weight . Eat good, nutritious foods and, after pregnancy , you will lose all the pounds you have gained. If you have a weight problem – if you are above or below ideal weight – you may need to follow a special nutritional program during pregnancy . Talk about it with your doctor.

Week 21 – 6th day

Transformation

Your uterus is in full expansion by displacing your center of gravity. Meanwhile, the relaxation hormone is softening all joints and ligaments in the body, including the ligaments that hold the pelvic bones attached to your spine. This will allow the pelvis to expand to accommodate the baby’s head in the correct position. All this causes pain and discomfort. Be strong! You can handle this!

Week 21 – 7th day

Your Baby

Your child is unique and nature prints marks that reveal this peculiarity. In his tiny fingers, for example, several grooves appeared, which will soon give rise to fingerprints. The eyelids begin to slowly open. It is as if the baby wants to know little by little the world that welcomes him.

The digestive system is already working at full steam. Part of its gears, like the small intestine, began to develop early, around the seventh week. Now another of her parts, the large intestine, has been activated through which a part of the amniotic fluid passes, which the fetus is continually swallowing.

Dreams in pregnancy

It is very common for future moms to dream about their baby during pregnancy. You may dream that your baby has a health problem, that he will not have everything ready before birth, and that after giving birth he puts the baby back into the uterus.

You may also dream that you are going into labor, that there is no baby or that it does not survive. Such dreams are not premonitions nor do they mean that something is wrong with your baby, your pregnancy, or you are doing something wrong. They are just the reflection of your anxiety and worries.

Administration of anti-D serum in pregnancy to prevent Rh isoimmunization

The pregnant woman with Rh negative blood type and who conceived a baby with Rh positive blood can produce anti-Rh antibodies. The production of these antibodies is a response of the mother’s immune system against fetal Rh positive blood, which is different from her own.

The Rh sensitization is more common during delivery (when the baby’s blood can get in touch with the mother), but occasionally can occur in late pregnancy.

The antibodies produced by the mother circulate for years in your body and, if you re-conceive, if the baby is Rh positive, these antibodies can destroy the new baby’s red blood cells, causing anemia and sometimes the death of the fetus.

The problem of sensitizing the Rh negative mother in future pregnancies can be avoided when she receives anti-D serum after the birth of an Rh-positive baby.

When is it given?

This medicine should be given at 28 weeks of gestation or up to 72 hours after delivery if the baby is Rh positive. Also in:

  • Cases of abortion ( spontaneous or provoked)
  • Ectopic pregnancy
  • Performing invasive maneuvers ( amniocentesis or chorionic villus biopsy)
  • External cephalic version ( external maneuver that helps the baby adapt to the position more favorable to vaginal delivery)
  • Placental abruption , placenta previa (placenta located on the cervix) Abdominal trauma or any other situation where the baby’s blood may enter the pregnant woman’s bloodstream .

Tips of Pregnancy

Do you feel more tired and weak than normal? If you are usually a dynamic person, this situation may affect you at a practical and psychological level, since your body forces you to different rhythms.

Your body is in a phase of profound changes , and it is through the “warning” of fatigue that it asks you to slow down, to act more calmly. This is a completely natural and common need in pregnant women. Nighttime sleep may be interrupted due to the child’s movements or the obstacle of the belly . In this case it is often helpful to resort to relaxing infusions before bedtime, and if the baby wakes up repeatedly, focus on your child and allow yourself to be “cuddled” by your movements. You can recover the hours of sleep during the afternoon.
