Yesterday at 2pm I drank half a bottle of 150ml castor oil to speed up labour. Nothing happened until about 9:30pm just lots of trips to toilet and then at about 1am mild contractions started. I've been getting them anyway and the contractions hurt more than before but still weren't strong enough to go to hospital. Since then I haven't really had any change except the diorhhea stopped. So I've just finished the rest of bottle about an hour ago. Has anyone else tried castor oil and if so did it work and how long did it take? Thankyoubxx
