! URGENTLY! Accuracy of term on US

[jktu]

Hello, Dear doctors!

stalknulis with such situation. At my sister last monthly were 24.10.2004. On Saturday 15.01.2005. Have gone or send on US on which to us have told or said, that pregnancy uterine, but term! 5-6 weeks!. By our calculations should be at least 10-11. How such can be and what to do or make further?

Probably, that pregnancy does not develop. Or she develops, but because of disturbance of a cycle real term has appeared less expected. It is necessary to repeat US in a week and all becomes clear.
