Why am I scared!

Amy
Okay on Aug 24 is was at a gestational day of 34 weeks 1 day. My ob did an ultrasound and stated I was 35 weeks and 4 days. My estimated due date went from Oct 4 to Sept 17. This is my 3rd pregnancy I I already know i will be having a c section (also my 3rd). But I scared to death with this one. Any one else feeling like me.
