Its been 6 hours since I started the black and blue cohosh and the clary sage oil and 4 hours since I took the castor oil. In the last hour or so, I've begun to have some painful contractions and a lot of gas. I was expecting to have diarrhea, but I must have a stomach of iron or something. Anyway, the contractions seem like a good sign. I'll let you know if any more developments happen.
