What is the normal cervical length?

The normal cervical length is usually 2.5 to 3 cm. The exact length cannot be determined because the cervical length of each woman is different, so the specific data cannot be calculated.

The cervix, which is a part of the uterus, is very important for women. It is also the place where the uterine cavity connects to the vagina. If any abnormality occurs, it will affect pregnancy. Because after a woman becomes pregnant, some hormonal changes will occur in her body, the length of the cervix will slowly change with the age of the fetus. Under normal circumstances, during a woman's menstrual cycle, the cervix will change and secrete mucus to keep sperm flowing, so the length of the cervix is ​​approximately between 2.5 and 3 cm. Once the cervix is ​​shorter than 2.5 cm, women will be more likely to experience symptoms of miscarriage. In this case, pregnant women should reduce standing and walking, avoid using abdominal pressure, and perform cervical cerclage between 14 and 16 weeks of pregnancy to prevent symptoms of premature birth. As the fetus grows, some parts of the cervix may become longer, and the length of the pregnant woman's cervix will probably be more than 3 cm.

In daily life, you should maintain a happy mood, pay attention to bed rest, avoid doing inappropriate and heavy physical work, have a balanced diet to ensure adequate nutrition for both your child and yourself, and go to the hospital for regular prenatal check-ups to understand the condition of the fetus in the womb.
