Shortened cervix... anyone else?

Jen • Mama to Savannah, born on 10.12.17

At my 32 week appointment today, my doctor told me that I have a shorter than normal cervix. He advised that I don't stand too long, lift heavy weights, or have sex til after the baby's born to prevent an early delivery. I've been doing all of those things up until now so I'm kinda bummed that things will have change til our daughter is born. Has anyone else been told they have this? And if yes, did you deliver before your due date?
