Cervical Length

Chambree
I'm 14 weeks and my cervix measured at 3.06 at yesterday's appointment. I know that's in the 3-5 normal range but I'm just a little nervous as I lost a baby 2 years ago due to incompetent cervix at 17 weeks. The specialist I see now doesn't seem to think that was the case so I just wanted to know has anyone else been in the same situation before?
