It doesn't prevent pre term labor at all, just incompetent cervix. I have a history of both (incompetent cervix can cause you to go into labor, but it's different than regular preterm labor). So, it won't prevent contractions, but it should help my cervix not dilate without contractions---when my contractions start getting more than 1-2 per day like they are now, my doc will give me meds to prevent and stop them.
But it definitely gives us a fighting chance.
