My 1st was born at 38 weeks, my 2nd at 39&4 days and I was told that the head of the one I'm currently carrying was fully engaged at 36 weeks - so I rushed home to pack my bag! I'm now 40 weeks & 5 days pg with an induction scheduled for this weekend! So I would say take nothing for granted - lots of 3rd babies are late apparently. I was sailing thru this pregnancy until I heard it might be early and it got me v impatient. My oldest son is now back at school but my 19 mth old is v out of sorts at home just now. Hope you'll be lucky and go early.
