delaying labor?

I'm aware of ways to help move labor along but is there anyways to help reduce labor? I'm relatively an active person so there's not much I can do on that end but I would prefer if my son just stayed cuddled in the womb for the next two weeks and not decide to come earlier than 40 weeks. I'm 38 weeks and have started some new symptoms and received mild contractions that are inconsistent at the moment. My OB believes I'll be late which I hope but I have very little pain tolerance. We also don't find out if I dilated any until next Monday. 😰
