Corpus luteum levels

Sara
Help! I just heard back from my doctor...this is my second opinion. I have been trying to get pregnant for almost 3 years now. She is saying that my hormone levels during my Corpus Luteum levels seem to be really low which is why I am having a hard time conceiving. Has anyone else had this issue and ended up pregnant? Is it a simple fix?! What did you do? I am desperate for any knowledge at this point. Thanks
