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.
Since the test will not get a positive result until enough HCG is present in the urine, home pregnancy tests work at varying points from the time of conception. According to the Mayo Clinic, most pregnancy tests will not show a positive result until at least one day after your missed period, or about 12 to 14 days from conception. The one exception to this rule is the First Response Early Pregnancy Test, which has shown the ability to detect pregnancy up to five days before your period.
