If you are pregnant then a home urine pregnancy test usually become positive within a couple of days after a missed menstrual period. If it's negative at that time then you may need to wait for at least two weeks after your missed period before you can depend on a negative result.
Negative Pregnancy Test and STILL Pregnant?
In some cases, low levels of HCG in early pregnancy are not high enough to register as positive, and you could get a false negative result.
A pregnancy test checks for the presence of the pregnancy hormone hCG or human chorionic gonadotropin in your body. hCG is a hormone made by the placenta and when you become pregnant, it takes some time for hCG levels to be high enough to be detected.
There are two pregnancy tests:
- A blood pregnancy test: Usually positive 3-4 days before the next period
- A urine or home pregnancy test (HPT): Usually positive when you miss your period
Test Results of the HPT Urine Pregnancy Test
- A positive HPT test means that enough hCG is found: PREGNANT
- A negative HPT test means that no hCG is found: NOT PREGNANT
- A "false negative" test means that your test is negative but you ARE pregnant. This usually happens when you test too early. Read more about a false negative test HERE.
- A "false positive" test means that your test is positive but you are NOT pregnant. A false positive pregnancy test happens extremely rarely. Read more about false positive pregnancy tests HERE.
