Cervix measuring 2.8cm at 20-week scan, should I be worried?

Hi there 😊
I just had my 20 weeks scan where they also measured my cervix (due to previous c section at fully dilated) and it was measuring around 2.8cm. They said it is ok as the cut off is 2.5cm. I do have a phone call with the consultant tomorrow to discuss if future scans are needed but I am panicking here now, thinking this is too close? 😔
Anyone can share their experience with this please 🙏 thank you

I would be requested a further cervical scan maybe two weeks after to check it’s stable at that length. I have a different reason for short cervix (lletz), and it’s severely short, but has remained about the same length for about 9 weeks now (25 weeks, last scan 14mm, first scan 11-14mm). Shortness in itself is less meaningful than a cervix that’s shortening over time, so a follow up scan could provide information and reassurance :)

Also, yes yours isn’t technically short in their measurement! But I’d still want reassurance to know that’s just its length.
