I can finally say that after nearly four years of frustration, my wife and I are expecting a child on March 9. (She's 9 weeks pregnant.)
We took the summer off from doing more treatments and so my wife could train for her 13.1-mile half-marathon walk. She remarked that she'd get pregnant while trained, and it happened. We spent our wedding anniversary getting the ultrasound and initial appointment done, and everything looks good. I'm still in shock that it actually happened. I'd honestly resigned myself to it. I'm so grateful for it to finally happen. Thanks for listening to me and bearing with me during the bad times. I will never forget it.
