It usually not associates with contraction pain. Cervical incompetence might also increase the chance of ascending infection that result in miscarriage or preterm birth.
Cervical incompetence is not easy to be diagnosed. In mid-trimester, doctor will use transvaginal ultrasound to measure the cervical length, short cervical length will have higher chance of miscarriage or preterm birth although short cervix sometimes doesn’t mean cervical incompetence. Chance of miscarriage or preterm birth could be reduced through cervical length monitoring in high risk group with corresponding treatment.
