I tried soy - 3-7 (120mg, 120mg, 120mg, 160mg, 200mg) and i bled from O day (which was 2 days earlier than usual and i nearly missed it on CD11) to AF. so just be aware it's not for everyone! I lost 1 cycle, but for me it was worth the risk as after 11 years you'll try anything once. But just be aware that it can screw your cycle up if it's not for you. GL!
