My doctor told me that they are open to inducing, because it's scheduled and they aren't waiting for u to go into labor spontaneously. Unless of course it happens before you get induced. Doctors are impatient.
I asked to be induced at 38 weeks. My doctor Induced me at 39+2 and had my baby that day. It doesn't hurt to ask. He probably will anytime after 39 weeks.
Just because you want to be induced on your due date doesn't always mean you will have the baby that day. I was induce and took THREE IN A HALF DAYS!!!! It was hell but sooo worth it. Try for a couple days before to be safe. Congrats, Goodluck, and safe delivery!!
