Information about the photo
The skin is very sensitive, reflexes start to work, the head still covers one third of the body height.


Your baby has doubled in weight this week. The internal organs are as good as ready and start to work. From now on, your baby will mainly only grow and become stronger. The skeleton still consists of cartilage (nice and flexible).
The foothills of the brain cells will connect in this week. This is very important for the intelligence of your child. The foothills of the brain grow out of this period into an extensive network of connections.
His head is now slightly rounder so that the eyes are more in the right place. The ankles and wrists are formed and the elbows and knees are in development.
Your child starts to yawn, yawn and stretch.


Maybe this week is the first visit to a midwife in your diary? Do you need it? Do not hesitate to make an appointment sooner.
You can now carry out a double test. This test serves for the detection of chromosomal abnormality (Down syndrome). The test is done through a blood test. Herein the content of PAPP-A and hCG is examined. The test offers no diagnosis, but only a probability calculation. The result is known within a week. (preferred test: week 10 or 11)
The flake test is possible this week. This test detects hereditary diseases and chromosomal abnormalities (Down syndrome, trisomy 13 or 18). The test is done via the vagina (11 weeks) or abdominal wall (12 weeks). Tissues from the placenta are taken to check the hereditary material. The result is reliable but does not give a definite answer about Spina bifida. There is a small risk (1%) when the test is performed via the vagina. The risk is slightly lower via the abdominal wall. The result is known within 5 to 10 days.
From week eleven to the fourteenth week it is possible to detect a chromosomal abnormality (Down syndrome) via a neck fold measurement. With an ultrasound, the thickness of the fetal fold of the fetus is measured. The result of the test is based on probability. In 3% of cases with a normal fold of the neck, the baby appears to have a chromosome or congenital defect. The result is immediately known.
In the same period (week 11 to week 14) a combination test is also possible. This test also examines the chromosomal abnormality (Down syndrome) but does this in combination with a neck fold measurement and a double test. The age of the mother is taken into account. The result of this test is also based on probability calculation. The result is known within a week.


Take a photo camera to the midwife and take some nice pictures. Always nice to see again later. If you have a digital photo camera, it is also nice to make a video when listening to the heartbeat of your child.
Do not forget to bring your cheat sheet.
If you get a print of the ultrasound, scan it on the computer. The material on which the echo is printed may fade. A good copy is therefore useful.
Turn the overview off, 'When do you arrange what?'
A pregnancy diary is fun for now and for later!
