I'm personally against being induced unless its medically needed. i dont hate on those who chose to do so either. i recently heard this girl talking saying that at 40 weeks the placenta starts to die off... and get weaker and can no longer support the baby as well. i thought it was crazy talk and just stopped listening, but now i cant get it out of my head. please tell me this isnt true
