Cervical length and time you gave birth?

At 23 weeks we were hospitalized for pelvic pain and pressure and seemed my cervix was getting “ripened” for birth becoming very soft and very low (when my OB said it’s suppose to hard and high) they measured the length of my cervix and it was 2.8 cm when it’s suppose to be 3.5-4 cm at 23 weeks. We’ve made it to 29 weeks so far and I was just wondering when I did research it said women with cervix lengths between 2cm to 3 cm at 23-24 weeks gave birth at 37 weeks. Has that happened to you all? Just wondering if we might have an early baby girl or if all that is true..

Edit* they didn’t do the stitch because they said they don’t past 24 weeks and I was literally only a day away from 24 weeks, and they said progesterone doesn’t really work. So I have nothing keeping her in but prayers
