Maria de la Luz, from Mazatlan, a city in Mexico, appeared on television and showed reported ultrasound scans which she says confirms she is six months pregnant with a baby girl.
'They told me it is a girl. Look, you can see her little face,' she said.
Maria, who did not reveal whether she had conceived naturally or through IVF, said she first suspected she was pregnant three months ago.
She told reporters, 'My legs hurt and I was vomiting and felt dizzy. Now they have done around 10 ultrasounds in a private clinic and in the (public) social security hospital. The doctors could not believe it.'
If Maria does give birth, she will hold the record for the oldest woman to give birth.
The record is now held by Maria del Carmen Bousada de Lara, who gave birth at 66.
De la Luz said some of her children were not happy with the news that she was pregnant, saying they told her she was too old for 'those things'.
Maria is expected to have a caesarian due to her age.
