I drank loads of the stuff last time from 34 weeks i think. I made sure to have at least 4 cups a day! Don't know if it had anything to do with it, but my labour was relatively easy, and my cervix dilated easily and very quickly. My Ob has told me not to start drinking it before 36 weeks this time - i think she's worried i might go early (i was on EDD last time- 1st pg) and too quickly this time!! Evan was born 3 hours after arriving at the hospital. I really believe it did help and i can't wait to get stuck in to it again this time around... although i don't much like the taste of it, i like thinking it's doing some good!!
