Activity will help baby's head engage, and put more pressure on your cervix, causing it to dilate and efface. Inserting evening primrose oil is also supposed to help with cervical ripening. A good romp in the sack has put me into false labor 3 times this week, so if baby's ready, I can definitely see it turning into true labor.
Activity is key. The more you move, the more likely contractions will continue and head in the direction you want. Energy creates energy. Good luck mama.
