Tu bebé tiene 12 semanas de vida y ahora se llama feto. Mide casi 6 cm. y está totalmente formado.
Los dedos de sus manos y pies están separados y comienzan a definirse las uñas.
El esqueleto continúa creciendo y los huesos están más fuertes, pero aún flexibles.
El sistema nervioso está madurando cada día. Se mueve muchísimo pero aún no puedes percibirlo.
La placenta ya funciona al 100% para alimentarlo. El útero ha crecido tanto que ya ha superado la pelvis y se puede palpar por encima del pubis.
El latido del corazón puede escucharse perfectamente por ultrasonido.
¿Qué me sucede esta semana?
Es posible que algunos de tus síntomas de embarazo hayan empezado a mejorar. Si es así, te sientes bien, con más energía y menos náuseas, lo cual te permite alimentarte mejor.
De ahora en más cuida tu dieta, pues comenzarás a tener una necesidad llamativa de comer. Debes cuidarte de los excesos y controlar bien tu peso.
La placenta produce, además de hormonas, una sustancia parecida a la melanina que puede hacer que tu piel se pigmente más en determinadas zonas como en los genitales, las areolas de tus pechos y la línea media del abdomen. Ten cuidado con la exposición al sol ya que pueden aparecer manchas en la piel de la cara llamadas cloasma gravídico que pueden persistir varios meses postparto.
What is the 12 week NT scan?
The 12 week scan is a routine ultrasound examination carried out at 10 to 14 weeks of gestation. During the examination, the fetus is seen by abdominal ultrasound. Occasionally the view is not clear and it may be necessary to perform a vaginal scan. At the first trimester scan they confirm that the fetus is alive, they assess the gestational age by measuring the crown-rump length and will also look for any major problems.
What is crown to rump length (CRL)?
The crown rump length is a universally recognized term, very useful for measuring early pregnancies. The CRL is highly reproducible and is the single most accurate measure of gestational age. Charts have been developed for this purpose, but some simple rules of thumb can also be effectively used. From 6 to 11 weeks gestational age, the fetal CRL grows at a rate of about 1 mm per day.
Crown Rump Length:
Gestational age = 6 weeks plus (CRL x days). For example, a CRL of 23 mm would correspond to a gestational age of 9 weeks and two days (6 weeks plus 23 days = 9 weeks and 2 days). Accuracy of CRL after 12 weeks in predicting gestational age diminishes and is replaced by measurement of the width of the fetal head (biparietal diameter or BPD).
What is the Nuchal Translucency?
The nuchal translucency (also spelled nucal translucency) is a collection of fluid beneath the fetal skin in the region of the fetal neck and this is present and seem in all fetuses in early pregnancy. The fluid collection is however increased in many fetuses with Down's syndrome and many other chromosomal abnormalities. It is called a 'translucency' because on ultrasound this appears as a black space beneath the fetal skin. It is this black space that you will see measured during the ultrasound scan.
Currently the most accurate non invasive test for detecting Down syndrome during pregnancy is the measurement of the nuchal translucency with an ultrasound between 11 to 14 weeks of pregnancy. This is normally less than 2.5mm and when seen increased (greater than 2.5mm, see image on the right) may indicate the baby has Down syndrome or may indicate another chromosomal abnormality. 95% of measurements will indicate a reduced risk
