Has anyone considered

What if God doesn't grant them biological children? I was more certain before that it would happen no matter what or how long I was waiting, but now my mind has somewhat entertained the idea that maybe it won't happen. Has anyone else felt this? Will you try to have a family with <a href="https://glowing.com/glow-fertility-program">fertility treatment</a> or adoption or foster care? Has anyone felt they would just move on with no children? Just wondering if im alone and how others process these terrifying thoughts.
