No, it works for some but really its the symptoms of taking that puts you in labor, not the actual substance. It can actually be harmful during pregnancy because it puts so much stress on your body which causes the baby to get stressed/: too many negatives that outweigh the "possibilities" its not worth it in my opinion keep that baby safe! Plus, baby will come when he/she is ready and its been proven that the longer they cook, the better they eat and sleep (:
