IMO, unless your health, or your baby's health are in danger some way from a natural birth, being induced is unnecessary.

If you need more information from your OB, make a longer appointment with him before he wants to see you next, write down all of your questions, and concerns and talk to him, possibly talk along a support person who might know about things, like a midwife or doula, or just a freind/hubby for some strength and support. If you're still not comfortable with his reasoning, don't do it. Just remember that you don't have to.

Good luck.
