Shortening Cervix

Ashley

So I had an ultrasound a month ago and my cervix was 4.19cm. Had another yesterday and my cervix was 3.07cm. Dr says we will do another in 1 month to check it again.

If it falls below 2.22cm they will have to put in a cerclage. I'm worried it will be too long and it will shorten too much.

Has anyone else had this problem?
