How much does hCG increase per day?
In most normal pregnancies, at hCG levels below 1,200 mIU/ml, the hCG level usually doubles every 48-72 hours and normally increases by at least 60% every two days. In early pregnancy, a 48-hour increase of hCG by 35% can still be considered normal.
Does a darker line mean more hCG?
A: A darker line on the HPT does not necessarily mean the hCG is doubling.

So, if your baseline level is higher than 5 mIU/mL, your doctor may order a repeat test a couple days later to see if the number doubles.
How quickly does hCG build up?
After you conceive (when the sperm fertilises the egg), the developing placenta begins to produce and release hCG. It takes about 2 weeks for your hCG levels to be high enough to be detected in your urine using a home pregnancy test.
