Ways to induce labor?

What are some natural way I can induce my labor? Some that are healthy and won't harm me or my baby... I know sex and walking but is there anything else I can do?? I'm already 1cm dilated and I'm beyond ready to get this over with. I have 3 weeks left and next week we are going to strip my membrane but its not a guarantee that it'll cause me to go into labor... any advice? Thanks in advance
