For the women who have successfully used castor oil to induce, what is the dosage you used? Also how long until it triggered labour? I asked the former question in Labour and birth but it is a little quiet over there and I only got a few answers.

At 11:15am I took the 3 teaspoon dose although I was silly and put the oil in the glass first so I only got 2 out of the 3 teaspoons at that time. I took a 3rd teaspoon at 6pm followed by a hot shower. I have had one BM but it was not soft and I feel like I will have another BM within the hour but I am not feeling loose yet. I just had a 4th teaspoon but I am worried about overdoing it. Any tips??
