Short cervix concerns - 28mm

[DBS94]

Evening

I'm currently 16+4 pregnant and under consultant for cervical length checks. I was measured via trans abdominal scan last week (15+4) and cervix measured 28.9mm

Does anyone have any experience of this? I know that's not classed as 'short' as such but it's definitely at the lower end of things. Consultant didn't seem too concerned and asked me back after 2 weeks for a follow up scan. Has anyone measured around this and not had to have any intervention and stayed around this length? Or alternatively if it has dropped slightly at my next scan should I be pushing for progesterone?

I was having scans like this every two weeks for a while. Doctors weren't concerned. If things change for you then they will put a cervical stitch in.

@Chanel05 thank you for your reply. Do you know what length yours was roughly?
