Kristy - hugs for you. IVF is such a difficult journey. The HCG is not something you create as such (not like progesterone say). It is the hormone released when the embryo implants into the endometrial lining. You are not doing anything wrong and to my knowledge (I could be wrong though) there is nothing you can do to increase the HCG. Talk to your FS and see if they can give you any answers (or at least clarify what the chemical pregnancy means). Take care of yourself.
