Mucinex trick?

Hey yall... how many of ya did the mucinex trick to get pregnant? Did it work on the first try? Or did it take a couple cycles? My bf and I have been trying for almost a year now. We had a miscarriage on Halloween and we really want our rainbow baby. If the Mucinex trick didnt work for you, what did? Any advice would be great. We really want our rainbow and Im getting discouraged. I am sure he is too, but he is a little more difficult to read at times. Please help!
