The fetus now gets permanent teeth, and fingertips
and toes get their final shape. The nerves in the brain
develop and enable the child to turn, turn, flush, kick
and hit. The fetus is getting stronger - and you can
notice that too!
The fetus in week 18
The fetus is now sixteen weeks old. It weighs about
220 grams and is about 18 cm from the butt to the head.
The eyes have taken shape where they should be and you
can see that the ears stick out a little from the head.
The immune system creates antibodies and is now in full
function. The gut is filled with waste, dead cells and
digestive fluids. This is called meconium (barnbeck) and
constitutes the baby's first stool.
Fingertips and toes take on their distinctive shape.
The nerves in the brain develop and give the fetus the
opportunity to turn, turn, squat, kick and hit. The
fetus is now so strong that you can feel well if it
kicks. Visit Bestaah

Permanent teeth grow behind the 20 milk teeth in the
palate. The fetus is not yet able to breathe on its own,
but it is constantly developing functional bronchioles
that have the ability to transmit oxygen.
The fetus grows more and more and can yawn and make
different facial expressions. It can even hiccup, and
this hiccup can feel like small dunks throughout
The fetus now weighs 10 percent of the final body
weight at birth and is half as far as it should be when
it comes to the world.
Being pregnant in week 18
Treat yourself to a massage this week. Maybe your
partner can help with that? It can be a nice way for you
to spend time together and be close to each other. Also
remember that intercourse is harmless this week as long
as everything is as it should with pregnancy. The fetus
is affected by you and your health, and well-being is a
key word here. Tell those around you, especially your
partner, what you need to feel good. Take plenty of time
in your everyday life and make sure you avoid stress.
The navel can sometimes protrude more than normal,
but there is no need to worry. Your body weight may now
have increased by three to six kilos, and then your
stomach will naturally be larger. The movements of the
fetus can be felt well in some and less in others.
First-time mothers may tend to notice this less than
those who have given birth before.
Good tips for week 18
- Feel if you notice movements. It is wise to be
completely calm when doing this.
- Get up slowly to avoid dizziness.
- Be open about your needs to those around you and
take your time in everyday life.
Things to think about
When you are feeling movements you may feel some
small tingling in the stomach. The movements can be
compared to a feeling of having air in the stomach or
bowel problems. This is one of the weeks you can do
ultrasound check. Enjoy the opportunity, after all, this
is the first time you see your baby this way. Remember
that even if you are informed about the sex of the
infant this can be misleading. Whether you are told also
depends on whether the fetus shows its genitals or not.
Usual pregnancy signs in week 18
- The uterus is straight below the navel.
- Firstborns may have difficulty sensing movements
in the abdomen, while those who have given birth
earlier may be more likely to feel this.
- The fetus may press the blood vessels that are
in the stomach, causing dizziness.
Sleep on the side to prevent stillbirth
Women should sleep on the side during the last three months of their
pregnancy to prevent stillbirth, researchers say in a new study.
In a study, where one looked at 1000 women. the researchers saw that the risk
of stillbirth doubled if the woman slept on her back during the third trimester,
BBC News writes.
Short of stillbirth
- Stillbirth is defined by WHO as the birth of a dead child from week 22,
previous death is referred to as miscarriage.
- 3-4 out of 1000 births are estimated to be stillbirths in Sweden, which
is 440 cases per year. This is a low number compared to other countries.
- If you have an increased risk of stillbirth, or feel that fetal
movements are diminishing or ceasing, you should contact your healthcare
- The most common cause of stillbirth is that the baby gets too little
nutrition from the placenta. Premature discharge of the placenta and
pregnancy poisoning may in some cases be the cause. Other explanations may
be malformations, chromosome abnormalities, infection, maternal illness,
coagulation disorders, umbilical cord complications and twins complications.
In about 25 percent of cases, the cause of death remains unknown.
The researchers looked at 291 pregnancies that ended in stillbirth and 735
women who gave birth to a living child. And now the authors of the study believe
that the position in which the woman falls asleep can have an impact. But you
should not worry if you wake up on your back, they say, according to BBC News.
- I don't want women to wake up on their back and think, "My God, I've done
something horrible to my child," says Alexander Heazell, who led the study and
is active at Tommy's Stillbirth Research Center at St. Mary's Hospital in
He thinks that you sleep longer in the position in which you fall asleep, so
it is important to keep that in mind.
- Besides, you can't do anything about the position you wake up in, but you
can decide what position you fall asleep in, he says, according to BBC News.
The study has been published in the British Journal of Obstetrics and
Gynecology (BJOG) and, according to BBC News, is one of the largest of its kind.
4 tips: Sleep on the side
- Place one or more pillows behind your back to help you stay on the side.
- If you wake up during the night, check your sleeping position and change
when needed, but if you wake up on your back, don't worry. Just scroll over
- Also sleep on the side during naps during the day.
- The right or left side does not matter, according to the study.
