If you test after your miscarriage, you might become confused because of the false positive pregnancy test result. On average, it takes approximately 19 days for the hCG levels in your urine to disappear after you miscarry. Please note that this is just an average length of time.
The serum hCG test can be positive as early as 7-10 days following conception. However, in some pregnant women, the test is not positive 7-10 days after conception. This is because the time to implantation (and production of hCG) can be longer in some women.
