Just wondering if anyone can tell me if it is normal for the cervix to start shortening once you hit 20 week. At my last US it had shortened 1cm from 4.8 to 3.5 which is still ok but I have been 4.5 since 15 weeks then all of a sudden it shortened a whole centimeter.

My Specialist said to not be concerned unless it gets to 2.5 or lower then we'll start talking about stitches etc. He also said he has seen women who are dilating at 28 weeks, I just hope to make it that far.

I am really not very comfortable with the thought of this after what happened last time.

Can someone please tell be if the cervix normally starts to shorten etc around this time? does it fluctuate at all? I am starting to be worried thats all.

Thanks
