Introduction

At 13 weeks of pregnancy, the uterine size may be approximately 100×75×80 mm. The uterus is the organ in which the fetus develops. A normal pregnancy lasts about 40 weeks. At 13 weeks gestation, as the fetus grows, the uterus gradually increases in size, typically reaching around 100×75×80 mm. However, the fetus is still within the pelvic cavity, so the abdomen usually does not appear enlarged yet.

At 13 weeks of pregnancy, the uterine size may be approximately 100×75×80 mm, although there may be some variation depending on individual circumstances. The specific analysis is as follows:

The uterus is the organ responsible for fetal development. A normal pregnancy lasts about 40 weeks. At 13 weeks gestation, as the fetus develops, the uterus gradually enlarges and typically measures around 100×75×80 mm. However, the fetus is still within the pelvic cavity, so the abdomen usually does not appear enlarged. Nevertheless, if the pregnant woman maintains a balanced diet and consumes abundant nutrients, leading to faster fetal growth, the uterine size may exceed 100×75×80 mm.

During pregnancy, it's important to maintain a balanced nutritional intake and consume foods rich in protein and vitamins to support healthy fetal development.

Will the NT value be larger if measured at 13 weeks of pregnancy?

The NT value at 13 weeks of pregnancy is generally larger. The NT scan is performed between weeks 11 and 13 of pregnancy to measure the thickness of the fetal nuchal translucency and assess whether the fetus has any abnormalities. The normal range for fetal nuchal translucency should be less than 2.5 mm. As the fetus grows and develops, the nuchal translucency thickness increases, so the NT value at 13 weeks of pregnancy tends to be higher than earlier measurements.
