Prepared or not prepared...

This is now the 3rd cycle of trying for #3.  Supposedly my fertile window starts tomorrow.  I just started Geritol yesterday. I started with the Raspberry Leaf Tea this morning, and I am going to pick up preseed and opk's from the store today.  Should that cover it?? I am brand new to preseed, but have read a ton of reviews that woman get pregnant the first time using it.  Praying this is our month!!
