It's a really tough situation to be in... I know a lot of how you're feeling as I was there exactly 18 months ago.
You have to follow your instincts... what's right for one person isn't right for another.
I also did a lot of reading of the research and talked to other people who'd turned down induction or been induced. Although some research said there wasn't a difference in CS rates, I know so many people who've had traumatic induced labours... a far higher proportion that have had traumatic spontaneous labours. I knew and know that's not remotely close to a scientific study, but it definitely added to the arguments I found against dates-based induction. I just couldn't find any indesputable evidence to show for sure that it's better to induce before 42 weeks... the studies that I found where fetal outcomes weren't as good after 42 weeks weren't remotely up to date. The consultant I saw concurred with this... she said many of the stats on long pregnancies leading to stillbirth were from a time when fewer serious medical issues were picked up at 20 week scans, so conditions remained undetected that ultimately led to longer than average pregnancies and stillbirth... but these were included in the stats for post-dates stillbirth, even though the long pregnancy wasn't the causal factor. Likewise, I didn't find studies clearly saying it was definitely
detrimental to induce before 42 weeks... so I felt I had to follow my instincts, which told me to wait for labour to start naturally, as I don't believe in medical intervention without clear medical necessity.
Sorry, it might sound like I'm trying to 'persuade' you, but I'm really not... I just wanted to add in a different perspective and share my experiences. You have to do what feels right for you.
I turned down induction at 40+12 (after a lengthy discussion with a consultant who went through the risks and benefits of induction v expectant management with me and basically told me at the end of our conversation that I was doing the right thing and my baby was 'probably just a 42 weeker), was monitored at 40+13 (all fine!) and went into labour just past midnight at 40+15. My daughter was born at home in the birthing pool at 40+17. She was 7lb 8oz and came at just the right time for her after a tiring but amazing 53 hour labour (3.5ish hours established, teeny 10 mins second stage).
The thing is, you need to feel comfortable with your decision... if you feel you want to go for an induction, then that's the right thing for you. What makes me sad is when people are induced because they don't realise it's a choice... you clearly know that and are balancing up all the information. That's the most important thing.
Good luck and I hope that whichever route you choose, everything goes smoothly.
