Hello and welcome! As far as the soy you take it like you would Clomid. Either days 3-7 or 5-9. Days 3-7 is to produce more follies and 5-9 is to produce 1 or 2 great follies. The amount you should take is double the amount of Clomid dosage. The one you posted has soy in it but isn't all soy so I would not take it. Do you have access to Walmart there (sorry I'm not sure). Is there any online vitamin stores that ship to you?
This is what I took:
