As I'm writing this she is in PACU (Post Anesthesia Care Unit) recovering and did indeed have endometriosis.
What this means to us is, as of now, we are not diagnosed with "unexplained infertility". We're praying that this procedure has removed any blockages and/or issues that could have been causing us to not get pregnant. I am VERY thankful to God that:
1) The surgery went great.
2) They found and successfully removed the endometriosis.
3) We have a renewed hope of having children.
Once she is coherent again, I'm sure you'll be seeing a new post written from her perspective. Also, if she'll consent to it, I'm going to make a post with the images (from the inside) and some explanations from the doctor about them (in hopes of maybe making the choice to have this surgery for someone else a little easier).
