The fetus is now defined as “child”. It sometimes sleeps and is awake sometimes. You probably feel its movements the most when you rest yourself.
Some women get fluid in the body during this period. It usually helps if you move around and also try to drink a little more, then also reduces the risk of constipation.
If your legs swell during the days, you can try to lie with your feet high from time to time. Also try support socks, they are available for purchase at the pharmacy.
Maybe you wake up in the middle of the night by spasms, it’s also a pregnancy scare – that goes over. Pressing the foot blade against a wall or headboard can counteract when the cramp sets in.
If you are a first-born, it may be only now that you begin to feel the baby’s movements;
Your breasts are also preparing for a small child, the milk glands have started to mature, the blood vessels in the skin become clearer. That some fluid comes from the breasts is perfectly normal, especially if you are a nurse.

As of week 22, the fetus is legally defined as a child if it is to be born, although the medical term is still fetal right up to birth.
Inside the abdomen, the baby now has a 24-hour rhythm. It both sleeps and is awake. Probably it is most lively when you rest.

Ultrasound, KUB and other fetal diagnostics
Through fetal diagnosis, one can assess the risk of chromosome abnormalities and damage to the fetus.
There are no fetal diagnostic tests that can guarantee that your baby will be completely healthy at birth. But there are methods that can show the probability of certain types of problems. Examples of this are ultrasound and blood analysis included in the so-called KUB test.
At the ultrasound, the pregnant woman finds out about when the baby (or children..!) Will be born and if everything looks good inside the womb.
Ultrasound is a painless, simple and harmless method, where you get a picture of the fetus or baby without having to pierce the skin during the examination.
All pregnant Swedish women are offered an ultrasound in v 18-20 today, and 99 out of 100 say yes.

The ultrasound can be made from the outside of the stomach, or vaginally, via the vagina.
During the examination you will find out if there are one, two or three children in the stomach. “Seeing” your child for the first time can be a momentous experience. Many people only now realize that there really is “someone in there”.
By measuring the different body parts of the fetus, the specialized midwife can date the pregnancy and calculate an approximate day of childbirth. You measure in slightly different ways depending on what week the mother is in:
Up to the week of pregnancy 12 you measure the seat height from head to tail.
From pregnancy week 13 you measure the width of the head and the length of the femur.
Another thing you can control with the help of the ultrasound is how the placenta is positioned.
Many fetal malformations can be seen in the ultrasound images, but not all. A directed, more accurate, ultrasound can be made after week 15 if there are suspicions that everything is not right.
Sometimes, several recurring ultrasound examinations are performed to check the child’s growth and weight gain.
In the case of bleeding later in pregnancy, the ultrasound may give an answer as to whether the fetus is alive, or whether it is a miscarriage.
NUPP and KUB
At an early ultrasound, during pregnancy week 12-14, you can make a measurement of the NACKUP clearance (NUPP) of the fetus in your stomach.
Neck clearing is the term for a thin fluid layer under the fetal skin in the neck-neck area that can be measured by ultrasound. All fetuses have such fluid, but a thicker layer increases the likelihood of a chromosome aberration.
If you also do a blood analysis a few days before the NUPP ultrasound, you get an even safer answer. Together, the method is called KUB (or CUB in English), which stands for Combined Ultrasound and Biochemistry.
By combining the results of the CUB tests with other risk factors, one can estimate how likely the child is to have a chromosome abnormality, such as Down syndrome. The risk factor that weighs most is your own age, but also your weight and any smoking habits are included in the overall probability assessment.
After the survey, you get a risk figure, such as “1: 3500” or “1:80”. The higher the number, the lower the risk of chromosome deviation. “1: 3500” means less risk of Down syndrome than “1:80” and means that ONE woman of 3500 pregnant with this risk level carries a fetus with Down syndrome, trisomy 21. The test also indicates risk level for trisomy 13 and 18, chromosome abnormalities that involves fatal injuries to the fetus.
If the probability is 1: 200 or higher (eg 1: 180) you are offered sampling from the placenta or amniotic fluid to get more knowledge about whether the fetus has a chromosome abnormality.
More and more people are choosing KUB
Many who undergo KUB examination are women over 35 who have been offered an amniotic fluid test, but who are worried about the increased risk of miscarriage after such a test.
If the likelihood of chromosomal aberration turns out to be high, these women can then choose to proceed with amniotic fluid tests.
Thus, all women are not automatically offered to undergo KUB. But in some parts of the country, the test has become very common even among younger women who feel uneasy.
However, it should be kept in mind that neither KUB gives any guarantees that the child is healthy, just a probability of whether there are deviations or not.
Amniotic fluid and placenta
Amniotic fluid and placenta tests are so-called invasive samples. They are done by inserting a needle into the uterus (via the stomach) and sucking out some water, or tissue from the placenta. The procedure is done under ultrasound control, it can be perceived as unpleasant but is usually not painful.
Tests are made from tests that can show chromosome abnormalities, for example Down syndrome.
Both amniotic fluid and placenta samples are also used as there is an increased risk of hereditary disease.
The most common type of analysis takes a few days to do, and the test response usually comes by mail. Here, the probability of deviations in chromosome 21 (which gives Down syndrome) as well as the fatal deviations in chromosomes 13 and 18. are checked
The placenta test is done at the earliest after pregnancy week 11, amniotic fluid test at the earliest after pregnancy week 14.
Sampling involves a risk of miscarriage, which is estimated to be about half a percent. The miscarriage may occur shortly after the test or several weeks later. Because of the risk of miscarriage, you should have a clear reason for doing the sampling. You should also think about how you would like to handle a response that shows the child has a chromosome abnormality.
Other samples that can be taken for fetal diagnosis
A blood sample from the prospective mother can be taken to see if there are antibodies against blood groups other than the woman’s own. Such antibodies can be found if the woman has had a blood transfusion with another blood group, or if she previously expected a child with another blood group. (The maternity center’s blood grouping card states that the antibody screening is negative if there are no such antibodies in the sample.) In
addition, in the mother’s blood and in the amniotic fluid, the level of antibodies against various viral diseases can be analyzed.
If the baby grows poorly later in pregnancy, a so-called blood flow measurement can be done in the placenta, to ensure that the baby really gets the oxygen and nutrition needed from it.
