13 week fetus HD boy picture

At 13 weeks of pregnancy, the baby's biparietal diameter is approximately 2.52 cm, the average abdominal circumference is approximately 6.90 cm, and the femur length is approximately 1.17 cm. The fetus's internal organs are nearly formed during this period. The embryo is approximately 9 cm long, with a top-rump length of approximately 7 to 8 cm. The sex of the reproductive organs can be initially determined, and the fetus's limbs can move. This time range is the time range for early screening of fetal malformations, and you should choose a hospital with better technical standards to do the NT examination.

The overall length of a 13-week fetus is about 10 cm, the biparietal diameter is about 2.5 cm, the hip circumference is 7 cm, and the weight is about 25 grams.

The development of each baby is different, and the standard value has a certain error. As long as the error range is not large and the prenatal check-up is normal, you can rest assured.

The biparietal diameter of a fetus at 13 weeks of pregnancy is between 2.3cm and 2.5cm, and the femur length is between 0.8-1.0cm. The baby weighs about 80 grams. At this time, the fetus is still in the early stages of pregnancy and is very prone to miscarriage, so you should be careful to avoid intense activities and strictly prohibit sexual intercourse. Eliminate crowded groups and reduce abdominal collisions. In daily life, you should also quit smoking and drinking, avoid contact with harmful toxic substances, and reduce the incidence of fetal malformations. Pay attention to nutritional balance in diet. Eating more apples and walnut kernels is beneficial to brain development.
