Todd Krieg can't feel anything below his chest after he was paralyzed in a dirt bike accident in 2014, so he and fiancee Amanda Diesen figured they'd need help conceiving a child someday. Not so: The couple recently found themselves unexpectedly pregnant, and their somewhat irreverent pregnancy announcement quickly went viral after they posted it on social media this week. It features Diesen, 25, holding an ultrasound photo as Krieg, 23, makes a triumphant face in front of a brick wall reading, "It still works!" "It kind of started out as a joke, because I was like, that's so inappropriate," Diesen tells People. "But we ended up doing it," says Krieg. Diesen got the idea for the photo while trying to find pregnancy announcements featuring dads in wheelchairs; one of the few she found featured the dad holding a sign reading, "I did that."
The couple met in September 2015 at a paralysis center in California where Diesen was working as a recovery specialist. After falling in love, Diesen returned to Krieg's hometown in Ohio with him. They currently live with his parents, and they tell Today they "definitely weren't trying to have a baby," figuring they'd get married first and then start trying in a few years. During their pregnancy announcement photo shoot, Krieg proposed. As for the mechanics of how, exactly, "it still works," Diesen explains, "Todd does not feel it when stuff is going on, but is occasionally able to reach climax." Krieg adds that, after one of those times, "We were like, 'Uh-oh, we should get a pregnancy test.'" In their contest entry for a Brides wedding competition, the couple says doctors told them it would be "nearly impossible to conceive naturally," but now a little boy is on the way in August. (Another moving pregnancy announcement.)
