A member asked:

U/s scan done on 10-28-2013 read as 6wks1day. does this put conception on 9-28/29? edd of 6-22-2014

A doctor has provided 1 answer

Yes: Although there is a range of accuracy with sonography - the later in a pregnancy, the less accurate (specific for dating) it is - at 6+1wks, it is accurate to within 2 days. So, your calculations are correct.
