I had early inductions for my first two and they were fine. First was 3hrs, second was 90min. I went into labour on my own at 40wks with #3 and he was a 2hr1min birth.

Dont be afraid, your educated on birth options so the likelyhood of a csection is already lower just from that. And regardless of being overdue or not; your other two were vaginal births so again even lower risk still.

I used clary sage oil and acupuncture to help make myself ready for labour and even then I was contracting and not dialated for hours before it finally kicked in with Ds3, then he was out in 2hrs!

Evening Primrose Oil capsule can help soften cervix too.

Good luck!
