Wacky Cycle Frustrations

Well, it seems like the Vitex doesn't want to work this cycle, which sucks.  I'm on CD 57 with patches of watery CM, but nothing that screams 'FERTILE".  I am ready to move on to my next natural option, Soy Isoflavones (SIs).  I have an appointment with my OB for the 28th to get my annual, some provera, and discuss the potential of Clomid in a few cycles if SIs don't work.  I definitely want to complete 6 cycles trying with natural methods before moving on to prescription medications to induce ovulation.  I am really hoping that SIs do the trick and I don't need to try Clomid or anything like that.
