Have sex, walk, enjoy a warm bath ☺
Lots of walking and acupuncture worked great for me.
Sex lol I know you probably hear that a lot but it really us the best thing. The sperm softens the cervix and it causes contractions. I went into labor with the my second after having sex at 42 weeks! Also, raspberry leaf tea which doesn't make you go into labor but it prepares your uterus for labor so that your contractions will be more effective in dilating you. You can also try doing lots of squats, walking, bouncing on a ball. Also just try to relax and don't stress. That baby will come when he or she is ready :)
