After the first three months, the priorities of the fetus are no longer a rapid development, but a rapid growth.


Your baby is already starting to get a little more body fat. He can now also capture sounds from the outside and startle them. All limbs are now formed and the chest muscles begin to move (just as if your baby is breathing). Your baby moves hard to make his body stronger. This week finger, hand and footprints arise.


Your stomach is getting bigger and maybe your clothes are getting tighter. Around this time you will have to come back to the midwife for a second visit. Maybe you're starting to feel your baby a bit.
From week 14 to week 18 it is possible to detect all abnormal numbers of chromosomes and check them for Spina bifida through a amniocentesis. With a thin needle, some amniotic fluid is removed from the uterus via the abdominal wall. In the cells of the amniotic fluid there is more reliable information about the chromosomes. By measuring a certain protein, Spina bifida can be determined. The test is very reliable and can prove Down syndrome with 100% certainty. There is a risk for your child from 0.5 to 1%. The result is known within two to three weeks for chromosomal abnormalities. Any neural tube defects are already known after five days.
