Hello! The normal cervical length is only about 30mm. When women have not given birth, the cervix will be round and firm. But when a woman is pregnant, the length of the cervix by week of pregnancy begins to change. From weeks 14 to 28 of pregnancy, the normal cervical length is from 30 to 35mm, this is considered a normal length. If the cervical length is less than 30mm, the cervix is ​​short and there is a risk of premature birth, especially for women with a cervix length less than 25mm.
I'm currently 26 weeks pregnant, 29mm cervical length ultrasound, I should go to a medical facility to check for any other signs along with the threat of premature birth. Experienced doctors will advise you on measures to prevent premature birth suitable for this gestational age
