Hi,
I've been having two weekly scans for cervical length due to previous miscarriages and cone biopsy. The first two at 16 and 18 weeks were pretty well the same at 42/43mm but not just within two weeks it's gone down to 36mm. I have another scan in two weeks time but just wondering if it is normal for the cervix to shorten so much that quickly. I do realise it's still within normal limits but just didn't know if the shortening so much was normal or not. Would love to hear your experiences and advice
