Supplements?

Okay ladies, i have been trying for a full year now! And have had nothing!! 
I have tried temperature checks, opks, and i used concieve plus lube for a while too, i also have used DIM (a herbal tablet) and folic acid... Nothing seems to help or even work. 
I was wondering have any of you or your friends using or have used anything to help push that BFP quicker?
