Short Cervix

I’m 24 weeks and a ftm with my baby boy 💙 I went into my doctors office yesterday and was told my cervix has went from 2.5 to 1.1cm I also have a bicornuate uterus which has caused a few other complications but baby is healthy and fine. I received 2 doses of steroids shots to increases baby’s lung development because there’s a great chance he may come early. Has anyone else dealt with this if so can you please tell me about your experience and when did you give birth? I’m worried but hoping everything will turn out fine.
