Introduction

Under normal circumstances, the fundal height at 28 weeks of gestation is 26–30 centimeters. At 28 weeks pregnant, the fundal height is typically located at or slightly above the level of the umbilicus. Fundal height refers to the distance from the top of the uterus to the top of the pubic bone and is one of the important indicators for assessing fetal growth and development. By 28 weeks of pregnancy, the fetus has developed to a relatively large stage.

Under normal circumstances, the fundal height at 28 weeks of pregnancy is 26–30 centimeters. The following is a detailed explanation:

At 28 weeks of gestation, the fundal height is typically located at or slightly above the level of the umbilicus (navel). Fundal height refers to the distance from the top of the uterus (fundus) to the top of the pubic bone and is one of the key indicators used to assess fetal growth and development. By 28 weeks, the fetus has grown considerably, and the fundal height generally increases as the fetus develops. Normally, the fundal height at 28 weeks of pregnancy measures approximately 26–30 cm. However, it's important to note that fetal and maternal growth patterns can vary among individuals, so some variation in fundal height is expected. Measurement of fundal height is usually performed by a doctor or midwife during routine prenatal checkups. The procedure involves having the pregnant woman lie flat on her back with legs bent or sit on the bed, after which the healthcare provider gently palpates the top of the uterus and uses a tape measure or ruler to determine the distance from the pubic symphysis to the uterine fundus. This measurement helps evaluate fetal growth. If the fundal height does not correspond with the gestational age, further assessment may be needed—such as an ultrasound—to determine fetal size, weight, and overall development.

If the fundal height is consistently too large or too small, it may indicate potential complications such as intrauterine growth restriction, polyhydramnios (excess amniotic fluid), or oligohydramnios (low amniotic fluid). In such cases, prompt medical evaluation and appropriate management are recommended.

Why does water break suddenly at 28 weeks of pregnancy?

Water breaking refers to the leakage of amniotic fluid through a rupture in the fetal membranes. Sudden water breaking at 28 weeks of pregnancy may be caused by intense physical activity, poor development of the fetal membranes, abnormal fetal position, bacterial vaginosis, cervicitis, or other factors. If sudden water breaking occurs at 28 weeks of gestation, it is recommended to follow medical guidance for treatment with medications such as dexamethasone acetate tablets and magnesium sulfate injection, while also ensuring adequate rest.

At 28 weeks pregnant, I feel the fetal movements very low, as if the baby is about to come out.

In general, feeling fetal movements very low at 28 weeks of pregnancy may be caused by a low fetal position, large fetal movements, fetal hypoxia in utero, threatened miscarriage, vaginitis, or other reasons. Patients should promptly seek medical attention at a正规 hospital to determine the underlying cause and receive appropriate treatment. In daily life, pregnant women should maintain regular eating and sleeping habits.
