Soy Iso and Mucinex? Help.

Helen

I'm 28 with one child (10) One of my girlfriends told me that her OB told her to take Mucinex. This is supposed to aid CM and help it become EWCM for the chance of having sperm live in it while awaiting the egg. She also mentioned Soy ISO starting of CD3-CD7. This is my second cycle TTC and would just like to get it right this month. Anyone have any luck or have heard about these methods?
