Worked for me for DD2. Membranes swept at 3pm and I was in labor the next morning. I was 38wk 5d. I've heard that if you body is ready for labor it'll work and if not, it won't.
Mom to two amazing DDs ('07 & '09) and a fur baby.
Gluten free since Nov '11 after non-celiac gluten sensitive diagnosis. Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
