A positive hCG means that a woman is likely pregnant. The blood level of hcG in a woman with an ectopic pregnancy usually rises at a slower rate than normal.

Those with failing pregnancies will also frequently have a longer doubling time early on or may even show falling hCG concentrations during the doubling period.
