There's lots of ways they say help. None worked for me sadly, but you can try the yoga ball, sex, hot bath, red raspberry leaf tea (herbal and not harmful), walking, going up and down stairs, raw pinapple (supposedly), the list is endless lol but hopefully something works for you! Worst case, you get induced. Maybe not what you want, but it's not as unpleasant as people lead you to believe. Good luck!
Nothing helped me. I walked almost two hours a night, bouncing on ball, doing daily squats. I was 2 cm for two weeks then got induced. Even sex sex sex nothing worked
