Shortening Cervix

Dee
Hey mamas,
Needing some uplifting and advice. Not sure if anyone has experienced this. But currently 16+5 and was told my crrvix measured at 2.64 cm after having some small bleeds. They said I have a shortening cervix and put me on progesterone suppositories. It's super scary because I'm also on strict pelvic rest which prettty much feels like bed rest to me. I'm just wondering if anyone has gone through this with success stories?? They won't offer me a cerclage until my next ultrasound only if my cervix continues to shorten and the bleeding stops completely.
