banned from adopting, calling to adopt? (x post w/ Catholic)

I was told that a calling = a desire + opportunities. I assumed that we were called to adopt based on the desire of my heart. But after 4 years of pursuing adoption (domestic, foster, international), I started to question if God really wanted us to adopt at all. Then last month, the door was permanently shut with a situation I'd rather not go into that pretty much prevents us from being able to ever pass another homestudy. Therefore, all future opportunities to adopt have been removed, right? Therefore, we can no longer say that God is calling us to adopt, right? He may have called us THROUGH adoption, but not TO it. ... Unless the only kind of adoption He wants me to really focus on is embryo adoption? I am discerning if God is calling us to a childfree life. I'm trying this lifestyle on as we are on hold awaiting our second transfer of our last two adopted embryos. I'm wondering what our next step may be if our Pixie Stix don't stick. I know I need to just wait and see, so I'm just trying to be open to the possibilities.
