For example, with a 35-week gestational age delivery, a weight of 2,250 g (4 lb 15 oz) is appropriate for gestational age but is still low birth weight. One third of low-birth-weight neonates – infants weighing less than 2,500 g (5 lb 8 oz) – are small for gestational age. [citation needed]
The blue line is the mean and the green area delimits the 3rd versus the 97th percentile. [1] Ultrasound image of the foetus at 12 weeks of pregnancy in a sagittal scan. Measurements of fetal Crown Rump Length (CRL). The embryo and fetus float in the amniotic fluid inside the uterus of the mother usually in a curved posture resembling the ...
Median AFI level is approximately 14 cm from week 20 to week 35, [6] when the amniotic fluid begins to reduce in preparation for birth. An AFI smaller than 5–6 cm is considered as oligohydramnios. [3] The exact number can vary by gestational age. The fifth percentile for gestational age is sometimes used as a cutoff value. [7]

Your little one: This week is right in the middle of baby's most active period, which is usually between 27 and 32 weeks, because they still have room to move around. Pregnancy Symptoms Week 30
The blue line is the mean, and the green area delimits the 5th and the 95th percentiles. [2] A: Gestational sac, B: Crown-rump length of embryo, C: Amniotic sac, D: Yolk sac. The mean sac diameter [3] can effectively estimate the gestational age [4] between 5 and 6 weeks, with an accuracy of about +/- 5 days. [5]
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]
The survival of the baby is reduced and high perinatal mortality rates between 40% and 95% have been reported. [32] Babies of abdominal pregnancies are prone to birth defects due to compression in the absence of the uterine wall and the often reduced amount of amniotic fluid surrounding the unborn baby. [33]
