Anyone with a short cervix expecting twins?

Em

I had a MFM appointment today and my cervix has shortened rapidly within the last two weeks. I’m now taking vaginal progesterone because I’m at risk of preterm labour. I’m 27 weeks + 5 days.

Has anyone been through this? How soon after a diagnosis did you deliver? Were you on bed rest? Did you do anything specific to help keep the babies in?

I’m so scared about viability if they’re delivered early.
