I used castor oil with my first and didn't go into labor until two days later lol all I did was crap nothing.

sex...squats...walking...stairs

Eggplant Parmesan. I ate it literally for dinner the day I was due with my son the night after and for lunch the 3rd day. Went to be induced the 4th day and they told me I was already having contractions and I didn't even know. I still asked to have the pitocin cuz I was done being pregnant but it worked for me.
