Women with TVU CL ≤25mm who will meet the inclusion criteria will be counselled by an obstetrician regarding the risk of SPTB as per standard of care. The patient will be given ample time to have all questions addressed and consider participation. If the patient agrees to participate in the study, the informed consent form will be signed and a copy will be given to the patient. Women who are eligible and consent to participate in the study will be randomly assigned to one of two groups: cervical cerclage (i.e. intervention group) or standard obstetric management (i.e. control group).
