it may just mean you are not as far along as you thought. the dates are just an estimate based on the start date of your last period. you could be up to two weeks less in which case the would only see a fetal pole or implantation site. you should have your levels checked to see if they increase and another ultrasound to see if it changes. a lot of times when it is early in a pregnancy things do not always show up right away. these tests are not infallible do not worry!

What is a Blighted Ovum (Empty Gestational Sac)? A blighted ovum (empty gestational sac) occurs when a fertilized egg implants into the uterine wall, however, the fetus does not continue to develop past the sixth to eighth week of gestation. There is continued development of the placenta and amniotic sac which produces hCG (giving the positive pregnancy test). Most women either do not know they are pregnant or find out within the first trimester that they have a blighted ovum (empty gestational sac).

Is pregnancy normal if you've had an ultrasound at 3 wks and see no gestational sac?

At three weeks you have likely just implanted (assuming ovulation and conception at two weeks) and there would be no sac visible. According to some websites, it can be seen as early as 4 weeks. Personally speaking, I had an early ultrasound at 4 weeks and no sac was visible. A gestational sac and yolk sac were visible at 5.5 weeks.
