Has anyone experienced short cervix before?

For about 3 weeks been experiencing contractions and they get really bad... even just from walking I get them really bad. (Not Braxton Hicks, but real contractions)

My doctor checked me to see if I was dilated yet she said no but not much longer because theirs a short time (I have short cervix)

I’m 27 weeks 5 days!

I’m nervous! I get the worst pain and worried about delivering this early!

My youngest was born at 33 weeks, my oldest was 36 weeks!
