I read, most mothers take it past 40 weeks. and there's no indication whether the baby pooped because they're over due or because of it
baby's poop with out castor oil all the time.
just research it A LOT before you try it.
It says it works for some and for others it doesnt. The only thing I why I dont recommend it is if baby poops in ur womb is bad for the baby. You can try also other natural ways to get into labor. For example exercise ball or walking every day for 30-45min, sex etc
