Hoping to avoid induction... thoughts?

HappyMama30

So, I am now almost 39 weeks based on our dating u/s WAY back at week 14. BUT, we had a dating u/s because this little one was a surprise, and I only had two irregular cycles after my last child was born (30 days and then like 44 days when we got our BFP).  So, we had a dating u/s, which gave us a due date of Dec 16.  However, based on last period our due date would be Dec 23. 

So, my potential issue is that if I do make it to the Dec 23 date I will technically be overdue and my Doc would want to induce.  But, what if that Dec 23 is really the best date of the two and I am not technically overdue.  I talked to my Doc and she said we'd wait and see.   No real answer.  I tend to feel they would stick with the date given from the dating u/s.  I want to avoid induction for sure.  No real answer to this I guess.  Anyone else with "two" possible due dates?
