Have sex. I know it is hard at this stage but me and my husband wanted to move things along so we had sex the next day I was in labor. Now I am not saying go crazy but if you can it does help,
Fresh pineapple, warm bath, walking. Although I think no matter what you do, they won't come til they're ready. I was induced at 37 weeks due to preclampsia, and it didn't work at all, they decided not to c-section me, so they sent me home and I had by baby at 39 weeks and 2 days, lost my mucus plug the night before. With my first I was a week overdue and I tried everything .
Walk or some type of mild exercise.
I walked a lot and within 2 days I was in labor
I used a birthing ball don't know if it was coincidence or not but I started using it then 2 days later labour started
