how to get labor going?

hey mamas! 39 weeks and 2 days with my first baby girl. i’m trying to keep going as long as i can to let baby girl come when she wants! but my ob said he won’t let anyone go over 1 1/2 weeks past their due date, and it doesn’t feel like she wants to come anytime soon. i’m so uncomfortable and every joint in my body hurts! the back pain is real! i’ve been 1 1/2 cm for 3 weeks now. i know everyone says you can’t do anything to help your body go into labor, and your baby will come when it wants or when your body is ready. have any of you mamas had success in getting your labor going or speeding things up? just looking for some little tips and tricks. 💓
