I want a baby but...

I've been trying to have a baby since I could remember. I see everyone else having baby's and I'm over here like, is it my turn yet. I have Endometriosis and wanted to know if there was any tip someone could give me. I've been trying to track my period but I'm irregular. My boy been wanting baby's to and has be so patient with me and understanding. Is there something I can do that we can do?
