Believe the sonogram.
Assuming you mean 2009 - you conceived Wednesday 30th July 2008 - 40 weeks before.

Jan 7, 2007
Two weeks after your start of menses in June 2008
Approximately Saturday, October 27, 2007.
Saturday July 14th 2007, roughly
Roughly Sunday 2nd December 2007
Between June 4, 2007 and August 12, 2008 there were 61 weeks.
35 weeks.
somewhere around 23rd May 2008 - it's 40 weeks before
It would be around 8 weeks before the ultrasound date, since you are not actually pregnant for the first two weeks. Pregnancies are dated from your last period. So period on day one, conceive around 14 days after that and therefore '2 weeks pregnant' at that date of conception.
