I started at 36 with 1500 mg/day orally. At 37 went to 2000 mg/day, but only because I forgot to take the 3rd dose....for the past few days have been taking 2000 mg/day.
I really hope it works. My OB (who is not against natural remedies--he was 1000% in favor of using castor oil for a slow labor with my first) recommends against things like black and blue cohosh because of uterine rupture risks. Considering I am trying to VBAC I don't want to put myself behind the 8-ball to start.
As of a week ago my cervix was shut up like Fort Knox. Hopefully things will be different on Wednesday when I get checked again.
