Anyone else had a short cervix??

Last Saturday I had a growth scan at 30 weeks just to check on baby and my fluid. Turns out my cervix was measuring at 1.8 when it was supposed to be at 2.4, dr then ordered me to go straight to L&D to check if I was contracting and risk of having preterm labor. Sure enough I get there and I’m contracting (can’t feel them much except for tightening)😓 he then ordered to give me steroid shot which hurt pretty bad, and got put on IV. At the end of the day my cervix went from a 1.8 to a 2.2, so now I got put on bed rest. Seriously terrified of doing anything from the fear of having this baby girl early!!! Anyone else on the same boat??
