A Mexican official Friday rejected a woman's sensational claims that she was due to give birth to nine babies in the coming weeks.

Karla Vanessa Castaneda Perez told El Universal newspaper she was scheduled to give birth by Caesarian section in Arteaga, northeast Mexico, in late May when she will be seven months pregnant.

The 32-year-old -- who claimed to already have a four-year-old son and six-month-old triplets -- said she was struggling to sleep over concerns about buying enough milk, diapers and clothes for the babies.

The story made international news but local health officials have since poured cold water on her amazing tale.

"She is not pregnant," Jorge Luna, secretary of health in the northern state of Coahuila, told AFP after authorities examined Castaneda Perez's claims.

Luna also said Castaneda Perez, who is obese, had not ever given birth to triplets.

"They have three children, but they are four, 12, and 15 years old," he said of Castaneda Perez and her husband, Juan Bernardo Garcia Morales.

Castaneda Perez had described her pregnancy as a miracle.

She told El Universal, "The delivery is scheduled for May 20, but the doctors told me I can hold out for another month and achieve the complete growth of the babies so that they do not spend much time in incubators. It is too early to think about the babies' names, first we hope everything goes well, the pregnancy was normal, although now I have got an internal injury from the triplets' Caesarian, but we are confident the birth will go well."

The couple has already appealed for public help to cover the cost of medical care. They have no social security or private health insurance and say they need help to pay for incubators for their nine babies.

The mayor of Arteaga, Ernesto Cepeda Valdes, said the town was prepared to provide necessary support during the birth. He said that neighboring towns were all "godparents" of the babies, so they would help the family.
