To induce or not?

Memes • Hi. I am 26 years old and a mother of a 7yr old son. My fiance and I are expecting our second child in Jan. 2018.

I went to my 39week apt yesterday and was informed that my DS is weighing in the 90th percentile at 8lbs and 10ounces. My OB gave me the option to induce this week. I said no because I'm not due until Monday, 01/22/18. As much as I'm ready to have this baby, I prefer to give my body a chance to go into natural labor. But, then again, if I wait too long he will only get bigger and my risk for a c-section will increase. I also hear that if you induce before your body is ready, that could increase c-section risk. I'm confused on what is best. My OB said she doesn't have any medical reasoning to force induction right now, so it's all up to me. Also, I'm not even a centimeter dilated yet. Please help! Any suggestions? Thank you.
