My first (and 5th) VBAC was 43w2d (23 days "late"). I ovulate 10 days later than the normal woman. They say that is a sign of infertility, but I am on PG #8. Ha! What do "they" know?
The latest baby, a 4th VBAC, I have had (all healthy) was 43w5d. He was a biggun', but it was the best birth ever!! Everything went splendidly.
My only complicated births were on their due dates; the csection and my 3rd VBAC. My quickest births were 10-15-23 days late.
They cannot MAKE you get a section because of post dates. They cannot just drop you, they may threaten it, as there is some law against that. You can wait until labor (doing kick counts twice a day) and then go in anywhere to VBAC. However, it isn't the best idea, it is sometimes the only way to get a VBAC/healthy birth for both of you.
With my first VBAC, they did NSTs twice a week until she was born. The birth went perfectly fine. Maybe you could tell them that you ovulate later than the average woman. Who can argue with that?
Yes, your baby sounded small enough the first time, I doubt this one will be huge. And, besides, I usually have 6-7lbers even going so late, except the almost 44wker. He was 9lbs3oz, and it went fine. He was big, but fine and healthy, as I was as well. Kymberli
