What should cervical length be at 19 weeks

[Abbie1992]

Hey,

I had my cervical length done at 16 weeks due to a bleed. Was measuring 3.9cm. Today at 19 weeks had another check and was only 3.4. I was told this is fine and not to worry no more checks need to be done.

I have since googled and seen it should be atleast 4-5cm at this stage. And I am worried that it went down from 3 weeks ago. Should I be concerned?

Thanks

Nope you shouldn’t be concerned, anything above 2.5cm is normal.

Have faith that you wouldn’t have been told that the measurement is normal unless it was normal!

Anything less than 2.5cm is a concern. Above that is fine.

Will they not give you a follow up appt if you are concerned? I would think they should if it has shortened in length within 3 weeks x

Mine was 2.6cm by 23 weeks and I was given progesterone pessaries to take daily until 34 weeks!

Mines currently 28mm at 20 weeks and they've actually stopped monitoring me because they don't think it's a concern anymore. Although I am on progesterone after it dropped to 24mm. The variation could just be different people's interpretation, one sonographer measured mine at 43mm in between the two measurements above which it definitely wasn't! I really wouldn't panic but ask for another scan in a couple of weeks if you're worried.

Ask your midwife too what she thinks but they should give you another scan

Another scan is absolutely not needed, the OP has had two completely normal measurements, your cervix will naturally slightly shortened due to the weight of a gravid uterus, also a 5mm discrepancy can be due to the limitations of an ultrasound. Responses like this as so silly, the HCPs were not concerned and would not have simply ignored an abnormal result, let’s not encourage extra unnecessary strain on the NHS when both cervical lengths taken were way above the normal parameter.

What @thetangleteaser said, those two measurements are totally normal and the variation is normal.

Hi I have been getting cervical length scans fortnightly. My 15 week scan measered 38mm my 17 week scan measered 37 and my 19 week scan measuredl 34 and I'm due for another in 2 weeks. The cervix is sapose to shorten during pregnancy but maybe not that quickly. Have you been getting scanned and what we're your lengths.
