I was induced at 38 weeks and twice at 39 weeks each time was very different. When I was induced at 38 weeks I had a very quick 6 hour labor after they started the pitocin. With the next two even though I was further along I had longer labors one was 19 hours and my last one was 22 hours. My longest one almost ended in a c-section because my sons heart rate kept dropping. It really depends on how ready your body is and how it takes to the cervadil and pitocin.
