A: A darker line on the HPT does not necessarily mean the hCG is doubling.

Only a quantitative blood hCG test can tell you more about the increase.

How light can a positive pregnancy test be?

Most early-result pregnancy tests can only detect hCG when it rises to levels of 25 mIU/ml or higher, which usually happens around day 11. By day 14, hCG levels are typically around 137 mIU/ml. For some women, however, they can be as low as 45 mIU/ml.

How dark should a pregnancy test line be at 3 weeks?
