What Uterus size first trimester of pregnancy?

In the first trimester of pregnancy, the uterus typically measures about 7 to 8 centimeters in length and can expand to about 5 to 6 centimeters in width. By the end of the first trimester, it may start to rise out of the pelvis, becoming more noticeable externally. The size can vary depending on individual factors, including the number of pregnancies and overall health. Regular ultrasound assessments can provide more precise measurements during this period.
