Sometimes walking helps get things going. And as others said, sex and nipple stimulation also can induce contractions. But mostly you just have to wait. I did all those things with number 1 and he was born just a few days before his due date. With 2, nothing helped. I was induced when he was a week overdue. On the plus side, that delivery went really fast. With number 3 I was trying to avoid going into labor because she was a scheduled c-section (breech). But I went into labor on my own the day before it was scheduled anyway.
