Miscarriage. If you had a positive blood pregnancy test then followed by a negative blood pregnancy test then this is consistent with an early miscarriage. Some people refer to these as a chemical pregnancy. This means you were pregnant the pregnancy did not last. This is very common. If you want to be pregnant you can try again.

Quantitive blood pregnancy test came back negative two weeks after missed period. How accurate is it? Should I still be worried about pregnancy?

Very accurate. The home urine pregnancy tests are also very accurate at 2 weeks after an expected period. Negative means not pregnant as of 2-3 weeks ago, but probably means not pregnant as of 1.5-2 weeks ago with these sensitive tests. So, if still having sex over the past 1.5-2 weeks, there is a chance of a brand new conception that is too early to cause a positive test result.
