Yes: First, sorry for your loss. Yes,the pregnancy test may still be positive 3 weeks after a miscarriage. The HCG level has to drop off, and this can take some time. The ultrasound suggests the heart stopped about a month before you had the ultrasound, or that you weren't as for along as you thought.

1 month: Pregnancy hormone can stay in your body for a month or more depending on the miscarriage and how much and when tissue passed. If its been a month after all tissue has passed, you can probably rely on the pregnancy test. To be sure, serial blood tests with HCG levels can be more accurate.

Very unlikely: A positive pregnancy test 2 months after a miscarriage is more likely to be from a new pregnancy. However it is possible to be positive 2 months after a miscarriage if the miscarriage didn't pass all the pregnancy tissue, and that tissue is still making pregnancy hormone. In this situation i order several blood pregnancy tests in a row to see if the number is rising and get an ultrasound.
