The body of Princess Diana showed no signs of pregnancy, Robert Chapman, the pathologist who carried out her autopsy, has told the inquest into the death of Diana and her boyfriend Dodi Fayed.
But Dr Chapman acknowledged that while her womb and ovaries did not show any of the normal signs of pregnancy, those would not have been seen if the pregnancy was less than three weeks old.
"No, I did not," he said on Monday, asked if he had noticed any sign of pregnancy.
"If one is dealing with a pregnancy the appearance will vary, depending, of course, on the duration of that pregnancy. But an established pregnancy will show as a change in the size of the uterus, a change in the thickness of the lining and the presence of a gestation sac."
Dodi's father, the owner of Harrods, Mohamed Fayed, says the couple were killed by British security services in a high-speed Paris car crash on the orders of Prince Philip.
Mr Fayed says Diana was pregnant with Dodi's child.
The inquest heard that Diana did not appear to have consumed any alcohol in the hours before her death, although tests showed that Dodi - who dined with her that night - had.
