Your
Scan
If you are at risk of premature birth, it may be useful to have a scan to assess the length of the uterine cervix. A cervical scan is usually done after an abdominal scan. This can be done at any stage from 16 weeks but is most useful if done sequentially at 17 and 21 weeks of pregnancy.
A transvaginal approach is the clearest way to best visualize the cervix.
The scan can be done at any stage from 16 weeks but is most useful if done sequentially at 17 and 21 weeks of pregnancy.
In general a cervix should measure more than 25mm at 16-21 weeks. If the cervix measures less than 25mm you should discuss it with the person looking after your pregnancy. We may recommend a further cervical scan in 2-3 weeks. If the cervix is less than 25mm there may be options to use progesterone or insert a cervical suture.

Honest Review of Our Patients
Excellent Team we met yesterday. From the wonderful and welcoming reception staff to meeting Belinda ‘B’. Belinda explained everything that was going to happen, made us feel really comfortable and relaxed. I could not recommend the clinic highly enough. Fantastic customer service and skilled medical team.

All the staff were really nice to us . At the reception, the girls were smiling and welcoming. We were late and they managed to give us another quick appointment without waiting. The Lady who did a Scan was really good and professional. I was able to ask all questions I wanted and she was really reassuring.
