I found this interesting article today: http://www.adoptivefamilies.com/articles.php?aid=1380. People can say so many hurtful things during your quest to create a family without realizing they are hurting you. And after an adoption, they don't stop, "You'll get pregnant now that you can relax since you have a baby." A couple's chance of conceiving after adoption is no greater than it was before the adoption. If babies or water was a magical cure to infertility, I think we all would have heard about it!
When we chose to build our family by adoption, it wasn't after years of infertility treatments. It was after just a year of trying to conceive, a ruptured cyst on my ovary (leading to a PCOS diagnosis), a deployment to Iraq, and a thyroid cancer diagnosis. A difficult road to get there, but once we talked about adoption, it took all of 20 seconds to decide that's how we wanted to build our family. And it felt right.
