i am so sorry u are going thru this!

i had a grade 4 placenta previa and vasa previa with my pregnancy. unfortunatley i had 2 big bleeds and DS was delivered at 34 weeks. we didnt find out i had vasa previa until the day before DS was born and no one could tell me what it was. it wasnt until i got home and googled it that i found out how serious it was. have u had any bleeding? to be honest if you can got to 37 weeks without any bleeding then thats great! otherwise if your ob is concerned and wants to deliver your baby at 34 weeks then there must be a reason. like the others have said have a chat with him and see what he says. there might be a reason why he doesnt want to go beyond 34 weeks. its a very scary thing to be bleeding especially in late pregnancy.

good luck. feel free to pm me if you want to know anything else
