The final final step for the final time (?)

I decided to have a exploratory lap done to check for endo as a last diagnostic step in our journey.  Surgery is 9/19 and I'm starting to freak out.  Not because of pain, or The Awful (bowel prep) but for the fear that I will know for a fact that I cannot have children.  It's a weird feeling, it's something I've wanted; an answer, but the fear of knowing for sure is sometimes overwhelming.  I'm praying that I do have endo, but a very mild case, at least I would have an answer and be a step in the direction of (hopefully) increase fertility.  I do so hope I'm one of those women who have this surgery and are pregnant in just a couple cycles.  Please Lord, let it be.
