I did. I didn't take the pill form but drank 3 servings of soy milk on CD 4-8. We had been trying for 2 years and had 2 m/c. I got pregnant the second cycle of trying this and am now 21 weeks along with a healthy baby boy.
Of course, with anything, I'm not sure if it was the soy milk or just our time but I know there is a lot of positive info. out there on this.
Good luck!!
Sorry, I am not familiar with it. I wish you luck though and truly hope things work out soon. Good luck.
