Re: 1-3 weeks
Pregnancy is usually measured in weeks from the first day of your last period. So to say "1 week pregnant" is kind of a contradiction, because your first week of "pregnancy" occurs before fertilization even happens. So, for example, if you got your period on December 1, and ovulated and got pregnant on December 15, on December 28 you would be FOUR weeks pregnant, not two.
That said, I am assuming you are asking if an ultrasound can pick up a pregnancy at 1-3 weeks past conception (aka 3-5 weeks pregnant). I think yes, if the doctor is looking for a pregnancy. I had an ultrasound at 4 weeks 2 days (2w2d after conception) and the ultrasound showed a thick uterine lining and a tiny spot, no bigger than a typed period. I certainly wouldn't have know what it was if the nurse hadn't pointed it out to me. As it turns out, I ended up miscarrying, so I don't know if a healthy pregnancy would have looked different at 4w2d. I know the nurse didn't seem concerned from looking at the ultrasound.
I hope you get the result you want!
