I start to feel uneasy after 41 weeks. The WHO say that induction post 41 weeks correlates to less perinatal death. I went post dates with Dd2 and 3. I was fortunate to be able to be able to have daily monitoring though. I was around 40+10 with DD2 and 41 weeks when I went into labour with DD3. I was booked for an induction at my request for 40+10 for each. But managed to go into labour before then. (dd1 was induced early due to PE)
