How big is the belly at 7 months pregnant?

The professional term for pregnancy is gestation, and abdominal size usually refers to abdominal circumference. At seven months of gestation, the abdominal circumference is approximately 87 cm, although there are individual variations. Abdominal circumference is primarily determined by fetal size. Seven months into pregnancy falls within the second trimester, during which the fetus grows rapidly, with a weight of about 800–1200 grams and a body length typically around 28 cm. The fetus lies curled in the uterine cavity, along with amniotic fluid and the placenta, resulting in an abdominal circumference of approximately 87 cm at this stage. Abdominal circumference can be further divided into upper and lower measurements: the upper abdominal circumference is about 90 cm, while the lower is about 80 cm. However, due to factors such as genetics and nutritional supply, fetal sizes may vary. As long as all indicators remain within normal ranges, there is generally no need for excessive concern. During pregnancy, any discomfort should prompt timely medical consultation to ensure the health of both mother and baby.
