Two knots in umbilical cord! Help?!

Sara
I went in for an ultrasound today and they found two knots in my son's umbilical cord. I am currently 29 weeks and they have bumped me up to two ultrasounds a week to monitor him, they gave me steroid shots just in case they have to send me in to the hospital to deliver. He said the goal is to have me make it to at least 37 weeks, so it sounds like I won't make it to 40 weeks. Has this happened to anyone else and if so, how did it turn out for y'all?
