tj_90... try not to worry about not seeing much at 3 weeks. Possibly some changes in the uterine lining at that point, but often it takes closer to 5 weeks before a pregnancy is picked up. The blood work will check to see how your hcg levels rise over the course of a few days and they will likely do another scan at about 5-6 weeks.
