Labor starters

What are some ways to get labor going? I know that nothing is gaurnteed I just wanted to hear some ideas. Other then the typical answers like walking, sex, acupuncture, or castor oil. Sex is becoming uncomfortable, walking haha..right I can't even makw it through the grocery store, not doing acupuncture, & I'm not drinking castor oil because I've heard it can cause the baby to poop in the womb..

Also I heard warm baths & swuats which of course I've been able to accomplish. Lol.
