What length should cervix be at 34 weeks?
Between 16-24 weeks, the cervical length is usually between 35 and 48 mm. A short cervix is defined as being less than 25 mm in length before 24 weeks. By 32-34 weeks, the cervix normally starts to soften and shorten, so by the mid-to-late third trimester, it’s normal to have a cervical length of less than 3 cm.
Does short cervix mean labor is near?
Pregnancy week by week Cervical length refers to the length of the lower end of your uterus.
