VerifiedYour health is my mission, your recovery is my joy.
The normal length of the cervix is usually about 2.5-3.0cm, but the specific length depends on the woman's physical condition.
The cervix is a part of the uterus, located in the lower part of the uterus, connecting the vagina. During pregnancy, the cervical length gradually decreases with the increase of gestational age, which is to prepare for childbirth. However, in non-pregnancy, the cervical length is usually fixed, usually about 2.5-3.0cm. However, during pregnancy, the normal range of cervical length may change. Generally speaking, in the first and second trimester of pregnancy, the cervical length should be greater than 3.0cm. If the cervix is too short, it may increase the risk of premature birth and miscarriage.
Cervical length is usually measured by ultrasound, which can provide an accurate cervical length value and help doctors assess the health of the cervix. If abnormal cervical length is found, doctors may conduct further tests to determine if there are other problems.
