A Canadian woman who did not even know she was pregnant gave birth on an international flight on Mother's Day.

Finally, the crossover we've all been waiting for: I Didn't Know I Was Pregnant meets Airplane!

Ada Guan was unaware she was 37 weeks pregnant when she boarded a flight from Calgary, Canada, to Tokyo, Japan with her boyfriend Wesley Branch on Sunday. In an ironic twist of Mother's Day fate, Guan disembarked that flight as a brand new mother.

Guan told Global News she'd been having stomach discomfort recently, however both a home pregnancy test and a doctor visit came back negative (get a new doctor, guys). Which meant it was a pretty big shock when Guan felt ill on the flight and told Branch, "Something fell out of me." SOMETHING = BABY.
