I thought about drinking it myself. Its one of those tales that it might start labor but there's no proof but it doesn't sound like anything Bad will come of it. You're really early though. I'd get your doctors approval to try naturally inducing before you drank it just in case it did work.
As far as from what I gathered it doesn't seem harmful to the baby, just that it may possibly help induce labor.
I would wait on more replies and see what other women say before you take it, or see what you can find by doing a little research.
