My wife had cervical cerclage at 20 weeks of pregnancy. Now, she is at almost 38 weeks and the doctor is resisting the removal of the cerclage. Last time the cervical length measured in the 24th week was 37 mm. We suspect that she is doing this to encourage C-section delivery. Should we get a second opinion in this case? My wife does not like to go in for a C-section unless it is extremely necessary. What to do now?
