When the doctor counts you as 7 weeks, they are counting from your last period. I figured if the ultrasound says 7 weeks, that is from around sep. 7th, the 1st day of your last period. meaning between sep. 18th thru sep. 24th could have got you pregnant. Likely the 21st. However an ultrasound of 7 weeks on 25th October gives you a due date of 13th June not the 3rd. See the Related Link for "conception-calculator" to the right for more.

Doctors measure pregnancy from the first day of your last period, but you don't conceive until two weeks after that. Your baby was conceived 3 weeks ago.
