I dont think there is any wrong or right answers with those questions.

For me personally my ob was happy to let me go until 40+10 thankfully i didnt get that far but it was close and im not sure weather i would have opted for one anyways, i choose to perservere with my vbac attempt unless bubs went into distress or I was in real distress i didnt have a time limit just went with it. It still i guess comes down to YOU and what you want to do the ob cant make you do anything you dont want to and if you havent made up your mind by 37 weeks so be it Guess i havent been much help but theres so much pressure on what others think you should do and what you think others would want you to do...maybe just play it by ear make up your mind when you really want to have no pressure on yourself and just see what happens?
