How long does it take for the cervical length to change?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am 15 weeks pregnant. I have a history of miscarriage in my previous pregnancy, as my cervix was open early at 19 weeks. My cervix length is 1.3 inches now, and I am monitored by ultrasound every two weeks. My physician said that cervical cerclage is needed only if the cervical length is below 0.9 inch. Since I had a miscarriage at 19 weeks, I am really worried about my cervical length. How long does it take for the cervical length to change? Is there a possibility of the cervical length to shorten within two weeks, causing a miscarriage, or will it take more than two weeks? Is it advisable to have ultrasounds every two weeks, or do I need an ultrasound every week for my case?

Please advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

Do not worry. Your doctor has suggested and put you on the right course of action. Cervix length of less than 0.9 inch causes preterm deliveries. It takes around ten to fourteen days for the cervical length to change; hence the advice to get an ultrasound once in two weeks is well and good. Repeating the scan every week is not going to help with the outcome. Also, if the cervix shortens in less than two weeks, your doctor can immediately place a cervical stitch and prevent miscarriage. I suggest you take lots of rest and stay hydrated. I wanted to know if you are on any Progesterone supplements? Take care.

Regards.
