39 weeks pregnant and taken 2 tea spoon castrol oil about 9 hours ago?

Castor oil will make your stomach hurt and you'll probably spend some time in the bathroom. Also it can cause the baby to have a bowel movement in utero which can cause the baby to develop infection. This isn't safe for you or baby and will not make baby come sooner. When the baby is ready then labor will start. Nothing you take will make it quicker. Please don't take any more. Try walking as much as you can in the next few days as that can help the baby get into position and help you to dialate. That is what I did with my daughter. A couple days of walking and I went into labor. Hang in there. Congrats!
