Can Castor oil induce labor when your 38 weeks pregnant?

Congratulations on your pregnancy. Don't use castor oil to try and induce labor as the side effects are not worth it, plus there isn't any actual proof that is will work. If you are looking for safe and effective, painless way to induce labor at home then maternity acupressure may be for you. Check out this website, I bought the book, only $29 and it worked great, well worth the cost of the book. I was 41 weeks along, the best part it actually helped reduce the pain of labor and it was well worth the cost of the book to finally meet my beautiful baby boy. I would suggest that you check with your OB/GYN before trying to induce labor at only 39 weeks though.
