I know you probably don't feel up for it, but having an orgasm (the contractions you get afterwards) try to keep them going with squats, bouncing on a ball, etc., that really helps to dilate you more, because it will push the baby down farther. I hope she comes on her own for you!!
The ball is great once labor starts. It felt great before that but didn't really help me. Squats are good too. Good luck
