"What is the size of a fetus at 6.5 months of pregnancy?"

A fetus at 6.5 months of pregnancy, or 26 weeks gestation, typically has a biparietal diameter of approximately 6.68 centimeters, a femur length of around 4.87 centimeters, a body length of approximately 30 centimeters, and a weight reaching around 800 grams. There can be some variations in fetal development size at 26 weeks of pregnancy, which are related to nutritional factors, congenital factors, and whether the pregnant woman has high blood sugar levels. Obstetric ultrasound measurements may also have some errors, often associated with the measurement angle or the technician's technique. Sometimes, when the fetus changes its position after some time or if a different doctor performs the examination, there may be slight differences. Generally, as long as the pregnant woman's examination results do not indicate any abnormalities on the diagnostic report, and the obstetrician finds no abnormalities after examination, there is usually no need for concern. The most important thing during pregnancy is to undergo regular prenatal examinations, follow the doctor's instructions, pay attention to weight and nutrition, and engage in appropriate activities. After each examination, the doctor will advise on the timing of the next examination and whether it requires fasting. Regular examinations are crucial.
