Fetal development at 14 weeks of pregnancy
At 14 weeks, the fetus is fully formed, but needs to grow and develop all organs and systems. Is already able to move, but the mother won't feel it at this stage.
The nails are beginning to grow on the fingers and toes and the baby already has fingerprints. The baby may already have some hair, eyebrows, as well as fine hairs on the body (lanugo). The sex organs are in development and doctors may be able to tell if it is a boy or girl through ultrasound.
As for the baby's developmental support system, the placenta is developing rapidly, ensuring the ideal amount of blood vessels to provide all the food the baby needs. The umbilical cord is already developed and carries oxygen-rich food and blood to the baby, in addition to carrying waste and poor blood in oxygen from the baby to the placenta.
Usually this is the last week to measure nuchal translucency. Through the ultrasound, the doctor will perform a more detailed test to detect signs of Down Syndrome and other diseases. If the mother is older than 35 or has a history of genetic diseases in the family, amniocentesis between the 15 th and 18 th weeks of pregnancy may be indicated.
