Quoting Kelly&Coralie:" Sex and nipple stim can "help" but nothing is guarenteed to start labor unless your body is 100% ready for it"
right. but there is no way know unless you try.
with my last baby i was deff NOT contracting or anything until after we sex. it literally started my contractions just minutes after. i deliverd my baby about 12 hours after sex...was in active labor for maybe an hour.. my conctractions were really irregular..
with my first i was in fact, have irregular contractions i couldnt feel and they said id proabbly be back to L&D that night, and sure enough, 25 minutes of nipple stimulation made my water break all over.
