To be honest - being a 1st time mum, induced before 41wks you are looking more a c/s than vb.
does having a big baby scare you? Cos you can always go into labour naturally and if it doesnt work out then elect for a cs.
I refused a late scan for DD for this reason... DD ended up being 4kg and posterior but birthed vaginally with vac assistance (no tears) after being induced at 40+12. the induction did not help... it turned my beautiful anterior placed baby posterior and gave me horrific back pain.
