“We were totally blown away,” Misty Wiggs says of finding out she was pregnant with her third child in April 2015.

For 12 years, Misty and her husband had thought that they couldn’t conceive any children. They’d adopted their first daughter in 2007. Six years later, Misty unexpectedly became pregnant with their second child. Still, it surprised the couple when another pregnancy test came back positive nearly two years later.
