What causes low HCG levels in early pregnancy?

What can mess up HCG levels?

Home pregnancy tests work by detecting the presence of human chorionic gonadotropin (hCG) in a urine sample. There are a few things that can cause a false negative reading, namely the improper use of the test, testing too early, using an expired test, or diluting the urine by drinking too much water in advance.

Can HCG levels fluctuate in early pregnancy?

What if my hCG levels are rising but not doubling?
