Has anyone ever been "diagnosed" with a short cervix before the 3rd trimester? I had this issue with my 1st child, this is my 3rd do as you can imagine the risk for preterm labor is a little greater. My 1st came right on her due date, 2nd daughter- 2 weeks early via emergency csection and now my son (only 24weeks) my cervix is just shy of being 3cm. Supposed to be 4cm
