That seems to early. Especially when you know you ovulated a week later than your baby "measured." It's called an average, people!! Some babies have to be bigger than average!!! geez.
You could always decline the induction next Friday, and if it goes beyond another week (two weeks after your "real" due date), then ask for it again. I have a friend who went into labor the same day she declined her induction and she was soooo happy she did. It was only 10 days after her due date.
