After experiencing severe stomach pains, a Californian woman went to hospital - only to give birth a few hours later.
Beth Clay, 45, had no idea she was pregnant, and had been working right up until the delivery. It's her third child, but the only one to arrive unannounced.
"The doctor feels sure that [the baby] was behind everything… behind my kidneys, behind my liver," Ms Clay told Los Angeles channel KTLA.
Ms Clay thought she had kidney stones when she went to the emergency room. Up until then she showed no symptoms, and even lost nearly seven kilograms throughout the pregnancy on a strict diet plan.
