At my 20wk ultrasound my cervix was 4cm. I had a growth and development scan at 34w6d and my cervix measured 3cm - DS was born 44hrs after this scan! At the time I was concerned that my cervix had shortened by a centimetre. I mentioned it to my OB at my 6wk post birth appointment asking if that was an indicator that DS was imminently going to be born. She said that for me it wasn't and that 3cm was plenty of cervix.
