Getting induced with my twins at 33+3!

Ladies, I'm a ball of nerves right now! My baby A has been growing smaller and has had elevated blood flow through his umbilical cord for quite some time now. Today at my scan his cord had increased in elevation. The OB at the MFM decided that to be on the safe side we will be inducing thursday night! Tuesday and wednesday will be the steroid shots and strep b tests. I've only had full term births until now so I'm so scared for my boys! The last time they did weight on A he was 3lb8oz, and the last time they did both to see a difference B had a pound or more on him than A. Any advice preemie mamas? About nicu stay how to calm my nerves on this or stories alike?
