I personally would not take it. Speak with your healthcare provider before taking anything.
I've only heard horror stories about taking it, it's the only thing I've sworn never to try and I'm on baby #5. Accupressure worked for babies #3 and 4 wish I'd heard of it before.
Omg I had my first baby just after my 17th birthday. My mom made me take that cuz I was having really bad back cramps and couldn't sleep for 3 days after taking taking it I was so sick. It did not make me go into labour. All it did was make sure I couldn't leave the bathroom for a good 6 hours of puking and on the toilet. Everyone is different. Best of luck.
There was a woman on here that told her story about castor oil. It was bad... I think it may have had life threatening consequences.
Of course, there may have been underlying conditions. Whatever you decide, please be careful.
I took it last pregnancy and had baby within 12 hours after taking it. I'm considering doing it this pregnancy as well.
I did with my daughter 6 yrs ago and had her 24 hours later. Took it the other day with my son and couldn't stop throwing up. I decided not to do it again.
I have never taken it but I know people who have. I wouldn't unless labor is stalled or you are overdue. It can be dangerous.
