Soy Isoflavones for BFP!

Just curious if anyone on here has tried soy isoflavones and gotten a bfp. I was watching a youtube video of a woman who was ttc for 18 months and got her bfp after just taking the SI for like 3 days. Apparently it works like clomid. She also left a link and the stats are prettyyy impressive so i dont know. What do you guys think?
