I've had two opinions from perinatologists two hours away from one another and they REFUSE to do cerclage unless my cervix length is 2cm or less. They won't rule out incompetant cervix but say without a doubt that my loss was due to preterm labor. So they're protocal is 17P and just measuring the cervix. I need some happy endings. I'm SO scared to wait and see. Please share your good experiences with me!
