Ok mommas i got a question!

I’m 37weeks+1day pregnant with my baby boy and only have 20 days left until my due date! He’s head down already. This is my first baby and don’t know much about this process but I bought some castor oil.. I’m impatient I know.. but this heat and being big does not go together well. I’ve done some research on drinking castor oil and there are some many different things said. Have any of you mommas done this? Did it work for you? How far along were you? How long did you labor? Was the baby ok?
