I find it so interesting to hear about how relaxed some OBGYNs are about due dates. I have had four different OBGYNs and four pregnancies, and never had a doctor wiggle around on a due date. After the 12 week dating one and the 20 week anatomy scan, it doesn't budge, even though I consistently measure 2 to 3 weeks bigger.

Has anyone had their OBGYN change a due date after the 20 week scan? Or, like me, once it was set it was set?

Ps how can I talk my doctor into doing this! Currently have a csection scheduled for 12/28 but I really want baby hear around the 20th (39 weeks is actually Christmas, so he wouldn't be here that early)
